Find the speeders speed with respect to the ground

Reference no: EM13648703

A speeder is pulling directly away and increasing his distance froma police car that is moving at 23 m/s withrespect to the ground. The radar gun in the police car emits anelectromagnetic wave with a frequency of 9.00*10⁹ Hz. The wave reflects from thespeeder's car and returns to the police car, where its frequency ismeasured to be 326 Hz less than the emitted frequency. Find the speeder's speed with respect to the ground.
