You are driving toward a concert at 50 mph. As you get close to the venue you can start to hear the sound. What is the percentage shift in frequency of the sound that you hear while driving relative to the frequency that you would hear if you were at rest (in other words, what is (f / f0) − 1)? Recall that the speed of sound in air is about 767 mph.

You are driving down the road at 15.6 m/s (35 mph) when an ambulance passes you with its siren blaring. The ambulance siren produces a frequency of 700 Hz. As the ambulance approaches you from behind, you hear a frequency of 730 Hz . The speed of sound in air is 344 m/s. What is the speed of the ambulance? The positive direction points from your car (listener) toward the ambulance (source). Express your answer in meters per second.

A police car drives past you with its siren on. While the car is approaching, you hear a frequency of 550 Hz. A Recalling that the speed of sound is 767 mph, what is the speed of the police car if the siren has a frequency of 507 Hz when neither you nor the car are moving? B What would the apparent frequency of the siren be if you were driving toward the parked police car at this same speed....

You're driving your new Corvette convertible and can clearly hear other cars driving nearby. One of these cars honks their horn and your car, with its apps and sensors, displays the horn sound as 760Hz. Your Corvette also registers the car as a Mustang with a car horn of 795Hz. You are stopped at a stop light when their horn blares. Another of your Corvette apps measures the air temperature to be 26°C. a) What is the speed of sound...
