Problem 2.38 An unmarked police car traveling a constant 95 km/h is passed by a speeder traveling 139 km/h. Part A Precisely 1.00 s after the speeder passes, the police officer steps on the accelerator: if the police car's acceleration is 2.70 m/s, how much time passes after the police car is passed by a speeder and before the police car overtakes the speeder (assumed moving at constant speed)? Express your answer with the appropriate units. t = 10 Submit...
