2)While standing at a point on the roadside shoulder, a police car chasing a speeder was approaching you at speed V. At that moment you hear the siren of the police car at a frequency of f’=560 Hz. When the police car passes, the frequency of the siren changes to f”=480 Hz. The speed of sound is vs=360 m/s. Express f” in terms of vs, f, and V where f is the frequency of siren produced (symbols only).
