19PRACTICE PROBLEM
A musician is playing a note of frequency 450 Hz on a stationary loudspeaker. The wind is blowing at a velocity of 14 m/s from the west to the east. Calculate what frequency the note would appear to be to an observer heading south toward the loudspeaker at a velocity of 20 m/s. Assume that the temperature T = 25°C.
