Solution

Verified by Toppr

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, the initial momentum of the system will be zero.

According to the law of conservation of momentum,

Initial momentum = Final momentum

so,

0=mv-MV

∴v=mv/M

= 1000.020×80

=0.016 m/s

∴recoil velocity of Gun=0.016m/s
