Name: Period: Due Date: AP Physics 1 Homework - Newton's Third Law A student performs an 2.0 2.0 experiment using two carts 1 and 2 on a straight track. Both carts 1.5 can roll without friction Position of Cart 1 (m) and are equipped with 1.0 Position of Cart 2 (m) 1.0 springs. The student sends cart 1 to the right 0.5 0.5 toward cart 2 which is initially at rest. Time (sec) Time (sec) The student uses motion detectors to measure the positions of both carts as functions of time. The carts' springs collide between times t = 2 and t = 3 seconds. The graphs of the student's data are shown, where "right" is considered positive. (a) Fill out the action/reaction, cause-and-effect table below for the interaction between the two carts. Since the carts are equipped with springs, the type of force they exert on each other is called "elastic force." Make sure your "cause" explains the agent, object, type of force, direction, and whether it is "push" or "pull". Cause Effect art + hasler Action Reaction (b) Which cart has the greater mass? What evidence from the graphs above supports your assertion? (Hint: it has to do with "change in motion".) (c) Using the graphs above, calculate the acceleration (including the direction) of each cart. Label the accelerations a, and a2
