Problem Set 9 Physics 1116 : Due Friday, 10/29/2010 Please write the names of any classmates with whom you discussed the homework problems at the top of your problem set Hint : For (c), think about y 1 and y 2 and what happens to each of them as t → ∞ . You should be able to solve the problem this way without doing too much unnecessary mathematics. 7. A mass m is moving with speed v is the + x direction and collides with elastically with a stationary mass which has mass nm , where n is some number. After the collision, it is observed that both masses have equal x components of their velocities. What angle does the mass nm make with the x axis? 8. This question relates to Lab #5. Make sure you work on this question BEFORE you show up at lab Do this question before your lab, and read through the Collisions I chapter in the lab manual Consider the following 2D collision between two identical pucks on a frictionless hor-
