A rigid ball traveling in a straight line (the x-axis) hits a solid wall and suddenly rebounds during a brief instant. The v,-t graph in Fig. 2.46 shows this hall's velocity as a function of time. During the first 20.0 s of its motion, find
(a) The total distance the ball moves, and
(b) Its displacement.
(c) Sketch a graph of ax-t for this ball's motion.
(d) Is the graph shown really vertical at 5.00 s? Explain.
