Show your work for solutions to questions that require calculations. Explain from where you start to solve the problem and show your math flowing from it for full credit. If you need more space to finish a question, write BPP (Back of the Previous Page) at the end of the space provided and then complete your work on the back of the previous page. For multiple choice questions, circle the letter which you believe to be correct (or best). In all problems, take the gravitational acceleration g = 10 m/s 2 . 1. The only force acting on a particle of mass M is a conservative one. As the particle moves from point A to point B in response to this force, the kinetic energy of the particle increases by 300 J. During this motion, the particle’s total mechanical energy a) Decreases by 600 J b) Is unchanged c) Decreases by 300 J d) Increases by 300 J 2.
