A rigid ball traveling in a straight line `the x-axis` hits a soled wall and suddenly rebounds during a brief instant . The `v_(x)-t` grap in . shows this ball `s` velocty as a function of time. During the first `20 s` of its motion, find (a) its displacement (b) the total destance the ball moves, and (c ) skerch a graph of `a_(x)-t` for this ball`s motion. (d) Is the graph shown really vertcal at `5 s`?
Explain.

A ball moves on a smooth floor in a straight line with a uniform velocity 10 m s^(-1) for 6 s. At t = 6 s, the ball hits a wall and comes back along the same line to the starting point with same speed. Draw the velocity-time graph and use it to find the total distance travelled by the ball and its displacement.
