A sports car is travelling along a highway at a constant velocity of 36 m/s [N] exceeding the speed limit. It passes an unmarked police car parked on the shoulder of the highway. The police car accelerates from rest, 3.0 s after the sports car passed it, at the rate of 6.0 m/s2 [N] until it reaches a velocity of 48 m/s [N]. It maintains this velocity until it catches up to the sports car.
