Given:
Mass of gun=M=100kg
mass of shell =m=0.020kg
Velocity of shell = v=80m/s
Recoil velocity of Gun=V=?
initial velocities of both gun and shell will be zero
so, initial momentum of system will be zero.
According to the law of conservation of momentum,
Initial momentum=Final momentum
so,
0=mv-MV
∴v=mv/M
=0.020x80/100
=0.016m/s
∴recoil velocity of Gun=0.016m/s
