Parts (a), (b), and (c) of Figure 2.10 represent three graphs of the velocities of different objects moving in straight-line paths as functions of time. The possible accelerations of each object as functions of time are shown in parts (d), (c), and (f). Match each velocity vs. time graph with the acceleration vs. time graph that best describes the motion.

During a race, you are running at a speed of 4.50 m/s. You want to pass a slowerrunner, so you increase your speed steadily (that is, with constant acceleration) to5.75 m/s over a time period of 3.00 s. What was your acceleration over this timeperiod, and what distance did you travel between when you started and ended theacceleration?
