POLICE On Highway 900, a police vehicle with its siren emitting frequency f = 1,785 Hz is chasing a getaway car. Both are travelling at the same speed, v. = 40.00 m/s, as they cross under an overpass. Driving away from the overpass the driver of the getaway car hears the siren directly at frequency f, and also hears a wave reflected from the overpass at frequency f. What is the frequency f, which the driver in the getaway car will hear? Take the speed of the sound to be 344 m/s.

While chasing the person who released all the ping pong balls, an astronaut is screaming at 694Hz while moving towards the miscreant at 5.2 m/s. The prankster is fleeing, but at only 3.1 m/s. The air on the ISS is kept pretty close to standard pressure and temperature, so the speed of sound is 343 m/s. At what frequency does the prankster hear the yell? Do not actually solve the problem numerically or algebraically, just pick the one equation and define the relevant knowns and single unknown.
You are driving down the street with your windows open enjoying the nice day. On this nice 20°C day, the velocity of sound in air is 343 m/s . You see a person sitting on a park bench and hear him whistling just after you drive by. If the person whistles at a frequency of 1450 Hz and you drive away at a speed of 17 m/s, what frequency of sound do you observe?
