Document Summary
No other reference material is allowed during the exam: for the problems, explain your reasoning as much as possible. Partial credit will be awarded, and correct answers with no work shown will not receive full credit: good luck! Question 1 (7 pts): the gure shows a plot of potential energy versus position u (x) of a conservative force f (x). A particle is at point x = b at t = 0, moving towards the left. We need more information to decide. (c) (2pts) what are the turning points for this particle"s motion? a, b, c a, c a, c, f b, d, e. Block 1, of mass 2m , traveling at speed v1, collides with block 2, and the two blocks stick together, beginning an oscillation with frequency . The collision happens in a very short time. (a) (2pts) what is the velocity of the two blocks together just after the collision? v1.
