Question

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 $330 m s ^{-1}$, find the time when $B$ will hear the sound after firing by $A$.

✓

Answer

Distance between the two observers $=1650 m$
Speed of sound $=330 m / s$
Time in which $B$ hears the sound $=$ Distance $/$ speed $=1650 / 330=5 s$
Thus, B will hear the sound 5 s after the qun is shot.
