Chapter 1, Problem 18EAP
18. FIGURE EX1.18 shows the motion diagram of a drag racer. The camera took one frame every 2 s.
FIGURE EX1.18
a. Measure the x-value of the racer at each dot. List your data in a table similar to Table 1.1, showing each position and the time at which it occurred.
b. 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.
