A person showing off their new sound system is driving towards a group of people at a speed of . The group of people is stationary. What is the observed frequency of the sound if the sound emitted by the car has a frequency of 421Hz?
You are driving your car by a very loud concert and moving at . If the frequency of a particular long note is 740 Hz, what is the frequency of the note you hear as you approach the concert? What is the frequency of the note you hear as you move away from the concert? The speed of sound in air is

A police car is at a red light. A car behind him foolishly tests his luck and runs the red light. The officer immediately flicks on his siren and begins to chase the car, accelerating at a rate of . The frequency of the siren is 500Hz. If you are standing at the red light, what frequency do you percieve 6 seconds after the police officer began chasing the car?
