An unmarked police car traveling a constant 95 km/h is passed by a speeder traveling 140km/h. Precisely 1.00 s after the speeder passes, the police officer steps on the accelerator; if the police car's acceleration is 2.0m/s2, how much time passes before the police car overtakes the speeder (assumed moving at constant speed)?
