Here,
Mass of gun, M = 4 kg
Mass of bullet, m = 10 g = 0.01 kg
Speed of bullet, u = 100 m/s
(i)
Initial momentum of the system = 0 kg m/s
Final Momentum of bullet = m × u = 1 kg m/s
(ii)
Let the recoil velocity of the revolver be ‘v’
Mv + mu = 0
=> 4v + 1 = 0
=> v = -0.25 m/s
The negative sign implies the revolver recoils in the direction opposite to that of the bullet.
