  1. Team Name: KT Explorations Inc. Available Funds: $375,576.3 Vehicle Name: Ethan and Rachel Mk1 Vehicle Parts List and Cost: TT 18-A Launch Stability Enhancers x4 $200 each Structural Wing Type A x4 $500 each TT-38K Radial Decoupler x2 $600 each “Thumper” SFB x2 $850 each Advanced Nose Cone Type B x2 $320 each Twin Boar LFE $17000 Rocomax Jumbo-64 FT $5750 Rocomax Brand Decoupler $550 Poodle LFE $1300 Rocomax X200-16 FT $1550 Rocomax X200-8 FT $800 Airstream Protective Shell 2.5m $600 FR-18A Stack Decoupler x2 $400 each Terrier LFE $390 ET-400 FT $500 FLT 100 FT x5 $50 each LT-2 Landing Strut x4 $340 each Radiator Panel x4 $150 each MK 25 Radiator Mount Parachute x3 $400 each MK1 Command Pod $600 1.25m Heat Shield $200 MK16 Parachute $422 FTX-2 External Fuel Duct x4 $150 Seperation 1 SFB x8 $75 each’ Radial Drogue Chute x2 $150 Mobility Enhancer $440 Strut Connector x3 $42 each Total: $43,480 + 10% tax = $47,828 Design Goals: The vehicle is supposed to make it to Duna and return safely. We have carefully constructed the rocket to have enough stages to make it to the planet and back. Launch Goal: We are hoping to send Jeb to Duna and return safely! We expect to orbit Duna and make a safe return from the planet, too. We want to learn and demonstrate how to perform interplanetary travel and make sure Jeb has a ton of fun during the process. Pilot Plan: What will the pilot be doing during the different stages of the launch? Are there different activities / maneuvers to be completed at different altitudes or stages. The pilot will be reaching an orbit around Kerbin, as he has done many times before. Once orbit is achieved, a maneuver will be set up so that the ship will be pushed along the direction of the orbit of Kerbin, towards Duna. Aerobraking and parachutes will be used once in Duna’s atmosphere, and upon landing, Jeb will pack the chutes. A similar procedure will be performed to make it back to Kerbin safely!
  2. We present to you Jebedina, the beloved wife and fellow pilot of Jebediah.💕
  3. Unfortunately, due to a sick pilot, we are unable to launch this vehicle and will be moving on to another mission while our pilot for this mission is recovering. Team Name: KT Explorations Inc. Available Funds: $225,576.30 Vehicle Name: The Big Mun Guy Vehicle Parts List and Cost: 1. MK1 Command Pod $600 2. MK16 Parachute $422 3. 1.25 m Heat Shield $300 4. FL-7200 Fuel $275 5.

AV-R8 Winglet x3 $1920 18. FTX-2 External Fuel Duct x3 $450 Total= $18,767 (10 percent Foreign Enterprise Tax)= $20,643.7 Picture to come soon of "The Big Mun Guy" Design Goals: For this design we would like to reach the Mun and return safely back to Kerbin and to do this we are using a lot more fuel compared to before and then adding asparagus coupling. Launch Goal: With this launch, we would like to figure out that we can use the orbit to fling us out to the Mun to land safely. We expect to receive the "Landing on Mun (and safe return)" for a reward of $250,000. Pilot Plan: The pilot plans to launch straight up to 100 m/s then tilt 10 degrees east. Then at around 15km turn to 45 degrees east to get into orbit as done before. He/she will line up to reach the Mun's orbit by turning until the periapsis is into Mun. He/she will land and explore the Mun then return to Kerbin by getting back into orbit to get back to the Kerbin kind.
  4. Launch Report and Debrief Launch Time: 23 minutes Team Members Present: Both Ethan and Rachel Play-by-Play: Turn SAS on Begin stage 4-solid state and liquid fuel engines At aprox. 100 m/s start to turn 10 degrees east and 15 km want 45 degrees Run prograde and burn until apoapsis at aprox. 70km Stage 3 occurs when solid fuel engines run out and liquid fuel engine still runs Cut fuel after 70km Let Jebediah relax until getting close to the apoapsis Stable orbit is achieved when the periapsis is over 70 km Orbit at 4 min and 40 seconds into launch Retrograde turn to begin descending Begin burning up and decreasing speed rapidly through the atmosphere At 2500 m the parachute was released and safe descent achieved at 6 m/s 32:30 Jebediah was safely on the ground and EVA 33:40 The Speedy Boi was recovered Photographs: Time-of-Flight: 33:40 Summary: This flight was a great success for Kerbin-kind and for KT Explorations Inc. Jebediah Kerbin and the KT Explorations Inc. team was able to achieve a stable orbit at a little over 70 km over the surface of Kerbin, and after enjoying the view for about 20 minutes, Jebediah safely returned to Kerbin with a huge smile on his face. To move forward, we must be able to figure out how to leave the orbit of Kerbin to make it to the Mun, Minmus, and beyond! Opportunities / Learnings: We learned how to officially get into the orbit, and how to return safely (no explosions or fire!). Strategies / Project Timeline: This enforces the idea that we can really make it into space and we have great opportunities ahead of us! We are ready to start the exploration of the universe to stay ahead of our competition and reach more unique milestones. We need to research the use of 'delta v' in order to help us escape the gravity of Kerbin and reach new places. Milestone Awards Presented: Launch to 10 km - $5,000 Manned launch to 10 km - $10,000 Manned launch to 50 km - $15,000 Achieving stable orbit - $20,000 Achieving stable manned orbit - $25,000 First Kerbal EVA - $60,000 TOTAL: $135,000 Available Funds: $100,000 - $9,423.7 + $135,000 = $225,576.30
  5. At the end of last quarter, I wrote a blog post about how I needed to change a few things because of the disaster that had come about in all my classes but especially physics. I feel that over the course of the past 10 weeks, I have changed the way that I learn and study. I find that I am more focused to get things done and understand them in a timely manner. I use all of the time given to me efficiently as well. Before this quarter, I found myself wasting class time and not doing the work that I needed to do in order to understand the content. Now that the learning is almost done for most classes and we move into the studying for exams during the last quarter, I need to remember the success that I have had during this quarter and continue it on. I know I can do it. We are now in the final stretch of high school and I am ready for it all. Until next time, RK
  6. Something I have always wondered is the way in which a cell phone works. Everyone has them in today's world so now I need an explanation to how they work in a physics sense. From what I understand, when someone talks into the phone, their voice is converted into a signal that is transmitted through waves and then back into sound on the other end. Essentially it sounds like a two way radio. The signal is a type of radio wave that in the end can be dangerous to humans resulting in various health issues in the long run. Are cell phones really worth it if we are exposed to even more radiation that we need to be? Until next time, RK

    Earlier this year, we learned that physics is everywhere. I think that most of us have realized that physics comes up in our daily lives on earth and also in space. One area that I have forgotten about when in comes to physics is how physics relates in the oceans. One major idea is the waves in the ocean that we can hear about. The high tides and low tides impact the shells that we can find on the beaches. Because of gravity and the moon, the tides are on a cycle for high and low tides. The waves that formed through energy moving through the matter of water onto land. The picture below shows how the waves are used in surfing (something that I will never do in my lifetime). It uses that basics of waves that we learned about last year and puts them into the water all over the earth. Until next time, RK
  8. We all know what a candle looks like when we burn it. The blue at the bottom is the heavier and cooler fire. Because of gravity, the blue is at the bottom while the hotter and lighter fire is towards the top. On earth, fire burns up and around and spreads because of the oxygen that it has access to. In space, because there is no gravity and a very low concentration of oxygen, fire burns in spheres and spreads quickly based on where it can get the oxygen. In the video below, fire in space is explained in further depth with baffling information about combustion as well. Until next time, RK
  9. Many people know about the infamous Bermuda Triangle because of the ships, planes and people that all go missing in the triangle. The Bermuda Triangle spans from the edge of Florida to Bermuda and then down to Puerto Rico. The disappearances that come about from the triangle are unexplained and this is not something new. In 1492, Christopher Columbus made note in a journal that his compass was not pointing north but decided not to alert the already worried crew. Some evidence has proven that in the triangle, there are certain areas that a magnetic compass will point towards true north instead of magnetic north. In addition to the changing compass, the weather in The Bermuda Triangle has reportedly been another crazy factor in this equation. Because of its location, weather can dramatically change over a short period of time. These weather changes have also been known to become violent which could add to some disappearances. There are still no actual explanation to the vanishing boats, planes and people in The Bermuda Triangle, but one thing is for sure, something fishy happens down there. Until next time, RK
  10. We all know that birds fly except penguins but they waddle which is better than flying. To fly, a bird must flap its wings to give it lift that is greater than its weight in order to get up off the ground. If the lift is not greater than the weight, the bird will sit there flapping its wings and look like a crazy bird. Another aspect that remains in the mix for all flying birds is the drag forces that go along with their flight. To fly to their destination quickly, a bird wants to minimize drag forces if possible. Drag forces can be a burden for all flying birds sometimes, but on the other hand, when slowing down to land, a bird likes the drag forces because they will help the bird land quickly and without injury. The statements above apply to all large and small flying birds. For larger birds, they often soar throughout the sky to save energy. This happens because they have larger wing spans that allow them to flap less to get the same amount of lift as a smaller bird. Now as for the penguins that waddle, they use their feet to shuffle along and stay on the ground. Until next time, RK
  11. Buoyancy is the upward force that is exerted opposite to gravity with a liquid. In the diagram below, buoyancy is shown acting against gravity keeping up with the laws of Sir Isaac Newton. Buoyancy is the reasons some objects float on the water and some objects sink. Because it is spring break and I am on vacation by the ocean, I thought it was fitting to look into buoyancy. A rock sinks right to the bottom while boats and kayaks float on top of the water. The video below shows how extreme people who kayak work the waters using buoyancy. Although I did not go kayaking, I watched those who did. They did not go to the extreme that the Olympic teams do, but they still had buoyancy on their side. The boats that we went on to dolphin watch were more like the one in the picture below. It still amazes me that a large amount of people can travel on a boat without the boat sinking or tipping. Until next time, RK
  12. Most people know what a monorail is but what is a Maglev Monorail? Maglev means the transportation system levitates and moves using extremely strong magnets. Maglev Monorails operate using the strong magnets to move the train that has no wheels. The whole concept that the magnets repel their like sides and attract to their opposites help to push the monorail to top speeds. In the United States there is a Maglev Monorail in California at General Atomics in San Francisco. Below is a video of a brief news reports on the Maglev Monorail in China when it completed its test run. Until next time, RK

    I have never heard of the word "luge" until today when looking at events in the Winter Olympics. Luge is a sport where there is a rider on a sled that is sliding down ice feet first. The objective is to get down the track in the fastest amount of time. They often look like this while racing... The rider has to fight air resistance to get down the track as fast as possible. They start at the top of an ramp and then have to go around turns until they reach the finish line. Although this may not seem like a dangerous sport, riders can reach speeds of 95 mph or more. In the 2010 Winter Olympics, rider Nodar Kumaritashvili died in a practice run hours before the opening ceremony. Because of his high speed, he flew off his sled into the air and hit a metal pole. Due to his death, track designers for the 2014 Winter Olympics designed a track that went uphill in some areas which would force riders into slower speeds. Riders rely on gravity and proper turn times to reach the finish line the fastest. Until next time, RK
  14. So, most of us in Physics C have reached a point where we start to think about college and how this class is going to help us in the future. From what I have heard, most of us in this class plan on going into something that relates to physics in some way whether it be engineering or just a normal physics major. In the classroom, there is a poster that has the 10-Best Paying Majors on it which sparked my idea for this post. In other math and science classrooms you can see posters like this one that try to keep people involved in these classes. STEM classes have components that are in the top paying jobs overall. More recent information says that the order of top paying jobs include a lot of engineering which includes a lot of physics. 10. Geological and geophysical engineering 9. Computer engineering 8. Mechanical engineering 7. Aerospace engineering 6. Electrical engineering 5. Chemical engineering 4. Mining and mineral engineering 3. Metallurgical engineering 2. Pharmaceutical sciences and administration 1. Petroleum engineering As I think about how hard this class has become, I realize that it will somehow help me in the future even if it just for the challenge of it. Until next time, RK
  15. I like to still believe that there is a Santa out there but everyone tells me it is absolutely impossible
  16. I hope he can do all of that and beat the school record this year!!!
  17. That looks like it takes a lot of skill! Definitely not something that I could do!
  18. I wouldn't want to be hit by either but maybe you could get some money out of the person that owns the Lamborghini and hits you
  19. I think you should talk to the people who run Webassign! We need an app!
  20. That is interesting, I forgot about this stuff!
  21. These past few weeks have been some of the hardest weeks in high school. College applications were due during this quarter and once those were in, there was a sudden loss of motivation to do anything at school. In every class, I have noticed that I simply try and if I do not understand, I leave it and pray that it will not be important to know for the future. Sadly, this method has proved to be extremely unsuccessful. Midterm week has proved to me that I need to refocus myself for the rest of this school year or my grades will continue to plummet all around. I have self diagnosed myself with "Senioritis" which is curable with hard work and effort. I need to majorly fix my time management for the next semester and hopefully that will help me as well! Now on to studying for the rest of this week and praying that I can get a good grade on at least 2 of my next exams! Third quarter here I come! Until next time, RK
  22. At Boston University, the College of Arts and Sciences offers a class called Physics of Food/Cooking. This class combines learning physics with cooking which every person, even those who do not enjoy science, will fall in love with. The professor, Rama Bansil, teaches her students about the basic principles of thermodynamics, molecular physics with a little bit of molecular biology as well. She uses her cooking techniques with science to create treats and relate them to the curriculum. A perfect example of the idea of physics in food is presented in the video above with a coconut ice cream shell. They use liquid nitrogen to quickly freeze and eliminate the ice crystals that would form with a slow freeze. In doing that, they end up with a creamy coconut ice cream shell! I really want to take a class like this in college! Until next time, RK
  23. Most people think of bowling and think about how much fun they have with their friends and family. For me, I think of bowling for a team with a focus on hitting every pin down for a clean game. Clean games equal good scores and good scores equal a happy Rachel. (Clean games are games with all strikes and spares) For the past 6 years now, I have bowled for the school and on weekends, I participated in a league to improve. Every season has its ups and downs and currently, I am in a hole that I cannot seem to get myself out of. Consistency is a huge key in bowling and if you do not hit your target on the lanes consistently, everything can go downhill. The game of bowling is also about choices. "Do I use this ball and stand at the center dot and hit the second arrow or do I throw this ball and stand 4 boards to the left of the center dot and hit two boards to the left of the second arrow?" A lot of factors impact your bowling but, one thing will always remain the same: physics. Every lane, no matter which oil pattern, has Newton's Laws all over it. The force that is equal to the mass times the acceleration shown through a grown man throwing a ball that can knock down the pins with a stronger force compared to a six pound ball that is thrown by a little girl. When the darn 10-pin in the corner does not fall down (the worst pin on the planet), the second law is acting on it because there is no outside force meaning that it will stay at rest. Finally, the third law is shown when you life the ball from the return, you are putting a force on the ball and the ball is putting a force on you. Same with the approach that you walk on, you put a force on the ground and the ground puts a force on you. Well that is all for now... Until next time, RK
