  1. Team Name: Garalles Conglomerates Members: Gareth Daunton, Clayton Kralles Starting Funds: $70,000 Notes: You represent a large conglomerate of varied high tech industrial firms who have come together in an effort to sweep in and take over the Kerbal space industry. Software tycoon Daunton and hired music video mogul Kralles fresh off a multi-year humanitarian effort to head the conglomerate as CEO, hoping his strong social and relationship skills would help temper the money-thirsty greed of the conglomerate’s financial backers in an effort to safely and efficiently monopolize the market. It is further hoped that Daunton’s digital integration skills will provide some side income for the firm through innovations yet to be discovered. The Kerbal government is keeping a close watch on Garalles Conglomerates as they are worried about a monopoly situation. As such, Garalles is prohibited from engaging in any joint ventures with the other civilian space exploration organizations.
  2. Team Name: Big & Low LLP Members: Jacob Bigenwald, Matthew Bartlow Starting Funds: $30,000 Notes: You are a small high-tech firm specializing in integration of varied technologies for military purposes. CEO Matt Bartlow started the firm as an offshoot of a personal research firm, taking the business private as he focused on high-efficiency rocket engines for national defense purposes. Shortly thereafter, military regulations required significant robustness improvements in all their products. Bartlow then hired Bigenwald to apply his groundbreaking engineering skills to improving product robustness. Something was missing, however, and when the two realized they were making great products but losing money, they hired a business manager to take over the daily financial aspects of the business (and remind them to tie their shoes each day). Due to Big & Low LLP’s background in engines, all rocket engines are half price for the firm.
  3. Team Name: Axburns Inc. Members: Katelyn Axman, Bobby Burns Starting Funds: $30,000 Notes: You are a small start-up business focusing on the creative and artistic vision of space travel. Funded by international corporate mogul Katelyn Axman and science innovator and constant czar Bobby Burns, the team is focused on not only achieving greatness, but bringing the public along for the ride through Axman’s engaging and dramatic narrative style as mission reports are compiled into dramatic short stories / serial narratives which provide a significant boost to the start-up’s income and funding levels. Further, due to Burns’s pre-existing endorsement deal with Kerbinite Fuel Systems, all liquid fuel is available to Axburns Inc. at half price.
  4. Hi Wendy! I believe you'll find all sorts of resources here that could be of assistance. Is there anything in particular you're looking for? Welcome, and make it a great day!
  5. Very cute walsh416... now make sure to get a full night's sleep!
  6. For the vertical component, let's assume down is the negative direction... You can solve for time in the air using the quadratic: and the quadratic equation, or make your life simpler and solve for vf first, then time. Once you know how long the projectile is in the air, use that time in your horizontal equation to find how far it travels horizontally. As for the angle with which it strikes, use the final vertical velocity component and the horizontal velocity component (along with a little trig) to solve for the impact angle.
  7. Glad to help -- why don't you show what you've done so far -- i.e., show the tables of information for vertical and horizontal motion that you've put together. That'll give me an idea how to guide you to a solution most efficiently.
  8. I'd start by making a table of information with the initial velocity, final velocity, displacement, acceleration, and time for both the vertical and horizontal components of motion. Once you have the information in the table, your kinematic equations will be of help. If you're not sure how to do that, the following video might be a great place to start:
  9. Oh my, I never thought to apply physics concepts to Frozen. I've got a new weekend activity with my girls!
  10. Excellent analysis bailliexx13. TONS of examples of physics in exercising... some of my favorites:
  11. Name: Navy to Deploy Electromagnetic Railgun Aboard JHSV Category: Electricity & Magnetism Date Added: 09 April 2014 - 07:10 AM Submitter: FizziksGuy Short Description: None Provided The Office of Naval Research (ONR) Electromagnetic (EM) Railgun industry prototype launchers is being evaluated at the Naval Surface Warfare Center, Dahlgren Division. Both General Atomics and BAE Systems have designed next generation prototype EM Railguns capable of increased firing rates. The EM Railgun is a long-range weapon that launches projectiles using electricity instead of chemical propellants and is under development by the Department of the Navy for use aboard ships.

  12. I thought it was Alicia that gave the 12-string that unforgettable sound!
  13. Nice example of a "unique" application of magnetism, Spencer!

    Cool link -- looking forward to checking it out when our skies clear up a bit!

    Shooting An Arrow

    Projectile motion, forces, conservation of energy -- it's all in there!

    Physics of Singing

    Wow, that's fast! Was Kristen on key? Ever wonder why we sound so good singing in small areas (i.e. why singing in the shower is so popular?)

    Physics in Precalc

    Tremendous overlap with math and physics... and I believe in math classes instead of just learning the component method of analyzing projectiles, you'll also explore them in terms of parametric functions!
  18. Very cool, an excellent and creative take on sound and sirens. The wavelength symbol is actually pronounced lambda (λ)
  19. I, also, enjoy analyzing movies to see just where they "go off the rails," physics-wise. Pirates of the Caribbean has a great clip that makes it easy to do a similar analysis:
  20. I'm impressed you were able to get it back up to speed... well done!
  21. Isn't it amazing how so much is confusing when you start learning something new, but the more you work at it, the more familiar and comfortable it gets? Kudos!
  22. Hi Sungy, The following may help you with putting all the pieces together... http://www.aplusphysics.com/courses/ap-c/videos/APCRotKin/RotKin.html http://www.aplusphysics.com/courses/ap-c/videos/MomentOfInertia/MomentOfInertia.html http://www.aplusphysics.com/courses/ap-c/videos/Torque/Torque.html http://www.aplusphysics.com/courses/ap-c/videos/APC-RotationalDynamics/RotDyn.html
