The mass of the pistol (m1)= 5kg
The mass of the bullet (m2)= 30g= 0.03kg
The velocity with which bullet is travelled (v1)= 50m/s
The recoil velocity of the rifle = ?
By the law of conservation of momentum
Momentum of pistol = Momentum of bullet
m1v1 = m2v2
5kg * v1 = 0.03 * 50m/s
v1 = (0.03∗50)5=1.55
v1 = 0.3
The recoil velocity of rifle = 0.3m/s
