You are driving down the highway at 14.9 m/s when you approach an automobile accident on the side of the road. To keep traffic away from it, a stationary police car has its siren going; to the police, the siren has a frequency of 1100 Hz. If the speed of sound in air is 332 m/s, what frequency (in Hz) will be heard by you in your car? If the relative motion in the previous question was reversed (i.e. if...
