When the radio was operating, the wind blew from west to east at a speed of 25 m / s.

When the radio was operating, the wind blew from west to east at a speed of 25 m / s. Determine the speed of sound propagation in this direction. The speed of sound propagation in air at rest is 330 m / s.

Given:

v = 25 meters per second – wind speed directed from west to east;

c = 330 meters per second – the speed of sound in air at rest.

It is required to determine the speed of sound c1 (meter per second) with a wind from west to east.

Since the wind and sound will move in the same direction (from west to east), the speed of sound will be equal to:

c1 = c + v = 330 + 25 = 355 meters per second.

Answer: the speed of sound during wind will be 355 meters per second.
