BackFIGURE EX1.18 shows the motion diagram of a drag racer. The camera took one frame every 2 s. Make a position-versus-time graph for the drag racer. Because you have data only at certain instants, your graph should consist of dots that are not connected together.
(II) In Fig. 2–40, during what time intervals, if any, is the velocity constant?
The position of an object along a straight tunnel as a function of time is plotted in Fig. 2–40. What is its average velocity between t = 0 and t = 5.0 s?

In Fig. 2–40, at what time, if any, is the velocity zero?
In Fig. 2–40, does the object move in one direction or in both directions during the time shown?
A cat walks in a straight line, which we shall call the -axis, with the positive direction to the right. As an observant physicist, you make measurements of this cat's motion and construct a graph of the feline's velocity as a function of time (Fig. E). Assuming that the cat started at the origin, sketch clear graphs of the cat's acceleration and position as functions of time.
A block is suspended from a spring, pulled down, and released. The block's position-versus-time graph is shown in FIGURE P2.38. Draw a reasonable velocity-versus-time graph.
FIGURE EX2.4 is the position-versus-time graph of a bicycle. What is the bicycle's velocity at t = 5s
FIGURE EX2.4 is the position-versus-time graph of a bicycle. What is the bicycle's velocity at t = 30s?
(II) The position of an object along a straight tunnel as a function of time is plotted in Fig. 2–40. What is its instantaneous velocity at t = 10.0 s?
