A speeder is pulling directly away and increasing his distance from a police car that is moving at 24.0 m/s with respect to the ground. The radar gun in the police car emits an electromagnetic wave with a frequency of 6.95×109 Hz. The wave reflects from the speeder's car and returns to the police car, where its frequency is measured...
