Reference no: EM13981742

Suppose you are assisting a policeman, who is sitting in stationary cruiser and is pointing his radar 'gun' at the approaching car. His detector shows the car's speed. Describe how you could use your sound data for the car's resting frequency f₀ and measured frequency f_F while moving toward the policeman to calculate the speed of an approching car (v_s) in order to check the reliability of the radar gun.
