When the bell in a clock tower rings with a sound of 473 Hz, a pigeon roosting in the belfry flies directly away from the bell. If the pigeon hears a frequency of 446 Hz, what is its speed?
Homework Answers
f' = f (v - vo / v)
446 = 473 (343 - v0 / 343)
(446 / 473) * 343 = 343 - v0
323.4 = 343 - v0
v0 = 19.6 m/s

A speaker on a car produces a 150 Hz sound wave when parked. The car starts to drive toward a pedestrian standing by the road, and the pedestrian hears the sound shift to 160 Hz when the car starts to drive toward them. The car passes the pedestrian and drives away from them. What frequency would the pedestrian hear as the car drives away? Assume the speaker continuously produces the same frequency, the car maintains the same speed, and the...
