A tourist is driving a car along a straight road at a constant speed of 21.5 m/s. Just as she passes a law officer parked along the side of the road, the officer starts to accelerate 3.50 m/s2 to overtake her. Assume that the officer maintains this acceleration 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
