The predominant frequency of a certain fire truck's siren is 1450 Hz when at rest. Take the speed of sound in air to be 343 m/s . What frequency do you detect if you move with a speed of 38.0 m/s toward the fire truck? What frequency do you detect if you move with a speed of 38.0 m/s away from the fire truck?

You are jogging along a straight road one day at constant velocity vo when you hear the siren of an ambulance approaching from behind. The frequency you hear is f1 = 756 Hz. You stop to take a break and the frequency you hear changes to f2 = 765 Hz. The ambulance then overtakes you and speeds away, and the frequency you hear is f3 = 680 Hz. The speed of sound in air is vsound = 340 m/s and...
