A cab driver is driving a car along a straight road at a constant speed of 15.0 m/s. Just as he passes a law officer parked along the side of the road, the officer starts to accelerate 2.50 m/s to overtake him. Assume that the officer maintains this acceleration. (a) From the moment the cab driver passes the officer, determine the time it takes the officer to reach the cab driver (in s). S (b) Find the speed of the officer as he overtakes the cab driver (in m/s). m/s (c) Find the total displacement of the officer as he overtakes the cab driver (in m). m (d) What If? Determine the answers to parts (a) through (c) of the problem, if instead of accelerating at the same instant the car passes him, the officer instead begins his acceleration 1.00 s after the car passes him. (Enter the time in s, speed in m/s, and displacement in m.) time speed displacement S m/s m Need Help? Read It
