Figure 2–55 shows the position vs. time graph for two bicycles, A and B. Which bicycle has the larger acceleration?

FIGURE 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.

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?

In a position-time graph, what does the slope of the line represent?

In a $\mathrm{position}-\mathrm{time}$ graph, what does the slope of the line represent?

Given a motion diagram showing an object moving at constant velocity in the positive $x$-direction, which of the following position $x$ versus time $t$ graphs best represents the motion?

Which pair of coordinates is commonly used to describe the location of an object in the local sky?
