Open Question
FIGURE EX1.18 shows the motion diagram of a drag racer. The camera took one frame every 2 s. (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.
Open Question
FIGURE EX2.4 is the position-versus-time graph of a bicycle. What is the bicycle's velocity at (a) t = 5s
