A shell of mass 0.020 kg is fired by a gun of mass 100 kg. If the muzzle speed of the shell is `80 m s^-1`, what is the recoil speed of the gun ?

Verified by Experts

We are given: m = 20 g = 0.02 kg, M= 20 kg,` v= 100 m s^(-1)`
We are to calculate, Recoil speed of gun, V
Using relation: `V= (mv)/(M)`
We have, `V= (0.02 xx 100)/(20)= 0.1 ms^(-1)`
