Solving a proof on an exam and looking for possible resources to bring to it

AI Thread Summary
The discussion centers on preparing for a challenging physics exam that includes a proof component. The exam covers the first four chapters of a physics textbook, and the participant plans to bring several resources, including "Physics Problem Solver" and "Physics for Dummies." They seek advice on potential proof topics and additional materials to enhance their preparation. A specific example of a proof mentioned is the apple and archer scenario, illustrating the relationship between projectile motion and gravitational drop. Overall, the conversation emphasizes the need for effective study strategies and resource selection to tackle complex exam problems.

Have my first physics exam Thursday which I am told consists of 6 questions and one proof.
I am curious on thoughts of what a proof on an exam may consist of, and it there is any pages or books I could reference to give me some basic proofs or ideas of what I may see on the exam and how to work them out.

For the exam I am allowed to bring in any book or paper material to which I desire, so anything but a computer, phone, etc...I plan to bring Physics Problem Solver, Physics for dummies, and My textbook: Fundamentals of Physics 9th-Halliday, to which the test is on the first 4 chapters: Measurments, Motion along a straight line, Vectors, Motion in two and three space. So if anyone could help me with what possible proofs may lay in waiting or reccomend any other resoursces I could bring to this exam, please do so. My teacher promises, and I have heard nothing other than, his exams are extremely difficult and consist of very complex problems, and will be nothing short of miserable for everyone. We are given an unlimited amount of time to finish the exam, but I don't feel like staying there and working on it all night.

Thanks in advance for any advice or insight.

Work-Energy Theorem.

Centripetal acceleration = v2/r towards the center if the circle.
 
The only proof I can think of off the top of my head is the apple and archer proof; the question is here: http://www.alexpleasehelp.com/online/problems/arrowapple"

To make it a proof, you basically have to show that as long as the arrow is fired at the apple at its starting position, and both the apple drop and the arrow is fired at the same time, the arrow will always hit the apple.

Hope this helps.

Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
