Police officer at rest at the side of the highway notices a speeder moving at 62 km/h along a straight level road near an elementary school. when the speeder passes, the officer accelerates at 3.0 m/s2 in pursuit. the speeder does not notice until the police officer catches up. now assume that the police officer accelerates until the police car is moving 10.0 km/h faster than the speeder and then moves at a constant velocity until the police officer catches up. how long will it take to catch the speeder?
