4.) An unmarked police car, traveling a constant 95 km h , is passed by a speeder traveling 145 km h . Precisely 1.00 s after the speeder passes, the policeman steps on the accelerator. If the police car’s acceleration is 2.00 fracms2 , how much time elapses after the police car is passed until it overtakes the speeder (assumed moving at constant speed)?

5.) Assume in Problem 4 that the speeder’s speed is not known. If the police car accelerates uniformly as given above, and overtakes the speeder after 7.00 s, what was the speeder’s speed?
