Does anyone have the answers with work for the 2005 AP Physics B free response section? anything would be greatly appreciated.

I'm taking the AP Physics section B test in about an hour (good luck to anyone taking that), and I have a relatively simple question to ask that I hope I can get answered in that time. In torque, why was torque established to be positive in the counterclockwise direction and negative in the...

1997 Calculus AB AP Test Answers NEEDED! hi. I am taking my 2005 AP AB calculus test tomorrow and i just completed 1997's AB test for practice and i was wondering if anyone had the answers for the multiple choice. If you could upload them for me, that would be great. Thanks

I have been having trouble with this kind of problem lately and I need to know if what I have done here is right (calculator problem but I have not evaluated anything yet): Let R be the region bounded by the y-axis and the graphs of y=\frac{x^3}{1+x^2} and y=4-2x a) Find the area of...

i don't know which data is the slope and which is the y-intersect Researchers at the university of Denver infant study center wondered if temperature might influence the age at which babies learn to crawl. Perhaps the extra clothing that babies wear in cold weather would restrict movement and...

Hi guys, I need help with the following problem I couldn't figure out: 1) A block of mass 2 kg slides along a horizontal tabletop. A horizontal applied force of 12 N and a vertical applied force of 15 N act on the block. If the coefficient of kinetic friction between the block and the table...

To prep for the upcoming AP exam, I got all of the AP Exams 1995-Present, but cannot find anywhere to check my answers for the free response sections online. Does anybody know if the answers are posted anywhere? :eek: this AP exam is going to be soo hard!

Hey guys. I am not sure where to post this and my knowledge of Physics is very lacking due to very imcompetent teachers at my school, and my lack of motivation to teach myself. That being said, I am going to be a senior in high school and I am planning to take AP Physics B. Problem is...

How did everyone do? :)

Just curious (and nervous bc the test is tomorrow) but is the equation sheet given on the multiple choice section or only on the free response part? Thanks for your help!

Do not talk about the Mulitiple choice exam. DO NOT TALK OR CONVEY OR ALLUDE TO THE MULTIPLE CHOICE PORTION OF THE EXAM AT ALL! Discussions of the Free response is permitted as of Friday or 48hours from 8AM Wednesday 5/5/04 That is not allowed because they recirculate that year after...

Hey everyone... since the AP Physics C Exam is coming up next monday I was looking for old exams online (multiple choice exams) to study from. I've been searching for days and haven't come up with anything. Does anyone know where I can find old multiple choice sections of the AP Physics C Exam.
