Team Name: Vargard Conglomerates
Members: Cristian, Zach L
Starting Funds: $100,000
Notes: Financed by interworld day trading superstar Vargas, Vanrgard Conglomerates is Vargas’s attempt to “give back” to the planet that has given him so much, and if he just happens to make a financial killing in the process, who is he to blame? Immediately following the signing of Vargard’s papers of incorporation, Vanguard hired his old high school classmate, Zach Lessard, to head the firm’s day-to-day operations. Lessard’s penchant for getting the job done, regardless of details such as legality and financial legitimacy, made him a perfect candidate to leave Earth and relocate to Kerbin, where even the word “extradition” is so hard to pronounce the Kerbal society avoids the concept altogether.
Due to the influx of off-world investment and potentially “shady” directors, Vargard Conglomerates is required to pay a 10% foreign enterprise tax on all purchases (all vehicle costs go up by 10% from list price), and any fines or penalties have a hefty 50% foreign processing surcharge.

Team Name: Ornefler LLP
Members: Dan, Jesse, Leighton
Starting Funds: $30,000
Notes: You are a small high-tech firm specializing in integration of varied technologies for military purposes. CEO Jesse Lefler 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. Lefler then hired Ornelas 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 business manager Leighton Temple to take over the daily financial aspects of the business (and remind them to tie their shoes each day).
Due to Ornefler LLP’s background in engines, all rocket engines are half price for the firm. Business Manager Temple has only been signed to a short-term contract, and is eligible to join any two-member team following his contracted release date of May 25th.

Team Name: Channarney Inc.
Members: Nate, Trevor, Anna
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 soccer star Nate “The Great” Charles, the team is focused on not only achieving greatness, but bringing the public along for the ride through Carney’s narrative vision and Weldy’s creative scientific genius. Public anticipation for their APlusPhysics-exclusive narrative is already high, even prior to their initial rocket launch!
Due to Weldy’s pre-existing endorsement deal with Kerbinite Fuel Systems, all liquid fuel is available to Channarney Inc. at half price.

Yes Rick. After you purchase the book, there's a bright red "Download" button. If you've navigated away from it, you can go directly back to the page by navigating to:
Once you've logged in, you should see a download button. If you're still having issues, shoot us an e-mail and we'll send you a copy by e-mail right quick. (E-mail address is on top of main APlusPhysics.com page). Thanks!

Aha. I understand. The integration your teacher is showing isn't the integration part of Gauss's Law, she's just using integration to find the charge enclosed by the Gaussian surface. If she had just told you the charge enclosed was Q=Pi*a*R^3, you could have put that right into Gauss's Law.
So to answer your question, when do you have to integrate to find the charge enclosed? When you're given some sort of charge density function instead of the total enclosed charge. To use Gauss's Law, you have to know what Qenclosed is. If it's not given directly, you need to figure out some way to find it, and in many problems, that will involve some amount of integration.

Hi Jess,
Gauss's Law is a law of physics, it's always true. However, as far as usefulness goes, it's only really useful for finding the electric field when you have a charge distribution that exhibits spherical, cylindrical, or planar symmetry. Some of the examples you'll find in the guide sheets (http://aplusphysics.com/courses/ap-c/tutorials/APC-EField.pdf) or tutorial video (http://aplusphysics.com/courses/ap-c/videos/APC-Gauss/APC-Gauss.html) include a sphere or shell of charge (spherical symmetry), a line of charge (cylindrical symmetry), and a plane of charge. Hope that helps... make it a great day!

Part e is quite difficult (beyond scope of AP-1) and I highly recommend using a calculator or computer for numeric simulation. You need to take your kinematic equations for horizontal and vertical and put them together into an equation with h as your variable. The bad news -- there is no easy way to get this equation into an expression for just h, but rather, you may have something like h+Btanh+3h^2/sinh = C That's not the equation, but you perhaps get the idea. Then plug that into a computer or calculator to find a numeric solution. Verify your solution works, and you're done.

Nicely done, Billy!

I think one of our jobs as professional educators is to open a door to the students to see what possibilities may await them if they continue their studies. Along those lines, many aspects of modern physics are exciting and interesting and really get kids to start thinking about the world around them. Though it's not prescribed in any of our state or district curricula, I love teaching very basic relativity as well as microelectronics. Relativity tends to "blow the kids' minds," and microelectronics provides just a touch of insight into how the computer chips that in many ways dominate our daily lives function.

Tried solving what?

That's a great question, and assuming you're talking about the first 10-12 seconds or so, I'm not certain. There are lots that could be said about Newton's 3rd Law with the guns, and conservation of momentum, but as you don't know the mass of the projectiles fired, I'm not certain what conclusions your instructor is looking for. There are TONS of examples of N3 Law and Conservation of Momentum being violated in this movie (which is fine, it's just for fun), but this isn't one of the examples I'd pick. I'd go with something closer to: https://youtu.be/fTqxFIpc1j4?t=38s

Hi Niha. I'm not sure why you're having trouble uploading images. If you post your question and then drag an image file into your question (see the bottom of the edit page) or link to it, it should show up. I'll try it here to test... Once you've uploaded the file, click the little "plus" button to insert the picture into your post.
Please note that you should be careful not to upload copyrighted questions from other sources, and also, if you can show what work you've done so far, it will all us to better see where you're getting stuck and provide more targeted assistance. Thanks, and good luck!

Hi Niha. A great place to start would be a free body diagram of the trailer. You have friction to the left (400N), and the tension to the right. You also know it is accelerating at 2 m/s/s, so you could write Newton's 2nd Law, F=ma, as T-400N=500kg(a), and solve for T.

Date Added: 2015-11-23
Submitter: FizziksGuy110 years ago Albert Einstein published a theory that revolutionized the way we think about the universe. In this video I'll show you how to prove its two postulates using easy-to-understand real-world experiments, and how even the simplest understanding of quantum mechanics can be used to wrap your mind around why time must slow down the faster an object moves.

Depends on what type of calculator you have. I use the "Solver" on my TI-85, but there are similar functions on most modern graphing calculators. On my TI-89 it looks like it's the "Numeric Solver." On the TI-84 it's under Math --> Solver.

Algebraically, separating out H would be a bit of a chore, and not one I really have the time to dive into right now (which is why the problem states that calculators are recommended).
