Question

A helicopter drops a paratrooper carrying a siren that emits a 555 Hz audible signal. The microphone (reciever) on the plane mon- itors the signal from the transmitter as the paratrooper falls. If the perceived frequency becomes con- stant at 446 Hz, what is the terminal speed of the paratrooper? Assume the paratrooper always remains below the helicopter and the velocity of sound in air is 343 m/s. Answer in units of m/s A helicopter drops a paratrooper carrying a siren that emits a 555 Hz audible signal.

Explanation / Answer

v = (f0/f-1)*c = (555/446-1)*343 = 427.78 m/s
