Unformatted text preview: two sets of graphs one above the other with time axes synchronized, and mark the time when the police officer begins to slow down. (b) At what time after starting from rest does the officer reach the car? How far has each vehicle traveled? [HINT: Use your velocity graphs to solve this part.] (c) What was the officer's acceleration while slowing down? Name 2. [Tapping a Rolling Ball] In the figure at the right is shown a strobe photograph of a ball rolling on a horizontal table. The image marked with a heavy arrow occurs at time t = 0 and the ball moves to the right at that instant. Each image of the ball occurs 1/30 s later than the one immediately to its left. On the graphs below, using the coordinate system shown in the figure, sketch qualitatively accurate (i.e., we don't care about the values but we do about the shape) graphs of each of the indicated variables. The time at which the "kink" in the path occurs is t = t1. a x a y...
