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 $A$ .

Open in App

Solution

Distance between observer $A$ and $B = 1650 m$
Speed of sound $= 330 m / s$
Time at which the observer $B$ hears the sound $=$ distance covered/speed
$= 1650 / 330$
$= 5 s$

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

Distance between observer A and B=1650mSpeed of sound =330m/sTime at which the observer B hears the sound = distance covered/speed=1650/330=5s
