3. A car traveling at a constant 39 m/s (-87 mph) passes a police car that is initially traveling at 25 m/s (55 mph). At the instant of the pass, the police car accelerates at a constant rate of 3.3 m/s in pursuit. We wish to find how much time elapses before the officer catches the car. (a) Identify the initial states when the car passes the police. (b) Define the final state or conditions which enable...
