Ther is a sound source that produces a sound with the frequency f=737 Hz. This sound source is moving at the speed of v2= 5.8m/s and an observer is movingat the speed v1=3.2 m/s What is the frequency of the sound that the pbserver hears when the sound source and the observer are moving toward each other? Use 343 m/s for the speed of the sound in the air.
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.
