Question


While blowing its horn of frequency 580 Hz, a car accelerates at 0.4 m/s2.

The car starts from rest by your side and moves away.

How long will it take for the frequency you hear to decrease by 5%?

Hint: Do not forget to include the time it will take for sound to reach you.

figure the velocity the car has to go to drop the sound by 5Percent. then, figure the time to get to that speed, then add the time it takes sound to travel that same distance back to you.
