An observer A fires a gun and another observer B at a distance 1650 m away from A hears its sound. If the speed of sound is 330 m/s, Find the time when B will hear the sound after firing by A.

Text Solution

Verified by Experts

Distance between the A and B = 1650 m
Speed of sound = 330 `ms^(-1)`
Time in which B hears the sound = Time required to traverse 1650 m Time required to traverse 1650 m = Distance / speed
Time required to traverse 1650 m = 1650/330
`therefore` Time required to traverse 1650 m=5 s .
So, В will hear the sound 5s after the gun is shot.
