Windy day

Classical Mechanics Level 2

Two friends A and B are standing 100 m apart. A shouts out to B. If the speed of sound is 300 m/s in air and the wind is blowing in the direction from A to B, after how much time does the voice of A each B?

0.344s 0.30s 0.333 s 0.3225s

The speed of wind does not effect the speed of sound in air.

Thus the time taken = 1/3 s = 0.33s
