2-60.  A marine biologist shooting a video of a rare species of fish uses the video data to produce the graph of the fish's position x plotted against clock reading t in Figure 2-33.

a.   What is the fish's average velocity between t = 0 and t = 8 s? b.   between t = 8 s and t = 10 s? c.   between t = 0 and t = 10 s? d.   Is your answer to c the average of your answers to a and b? Explain. e.   What is the instantaneous velocity at t = 8 s? f.   Estimate the instantaneous velocity at t = 5 s.
