Chapter 2, Problem 2.9(choose chapter or problem)
A ball moves in a straight line (the x-axis). The graph in Fig. E2.9 shows this ball’s velocity as a function of time.
(a) What are the ball’s average speed and average velocity during the first 3.0 s?
(b) Suppose that the ball moved in such a way that the graph segment after 2.0 s was -3.0 m/s instead of +3.0 m/s. Find the ball’s average speed and average velocity in this case.
