ANSWER: a b c d e f Correct. First the ball moves with constant speed. Then, as it rolls down the ramp, its speed increases linearly. The ball encounters another flat section, and its speed is once again constant. Finally, as the ball rolls up the ramp, it decelerates. Part D Select from the graphs pictured the one that most plausibly represents the graph of x acceleration vs. time. (Note that the origin of the y axis of the graphs is arbitrary; zero acceleration is not necessarily at the bottom of the graphs.) ANSWER: a b c d e f Correct. Initially, the ball's acceleration is zero. When the ball rolls down the first ramp, its acceleration becomes positive and constant. When the ball encounters the second flat section, its acceleration is once again zero. Finally, as the ball rolls
