Example 2-17 depicts the following scenario with the accompanying figures. A speeder doing 40.0 mi/h (about 17.9 m/s) in a 25 mi/h zone approaches a parked police car. The instant the speeder passes the police car, the police begin their pursuit. The speeder maintains a constant velocity, and the police car accelerates with a constant acceleration of 3.3 m/s².
