Since no external force acts on the rifle, the change in momentum is zero.
Mometum of rifle = Momentum of bullet.
4 x V = 0.050 x 35
V = 0.44 m/s.
Mometum of rifle = Momentum of bullet.
4 x V = 0.050 x 35

mass of gun = 4kg
Mass of bullet = 50g or 0.05 kg
Velocity of bullet = 35m/s
=> momentum of bullet =
0.05×35
= 1.75kg m/s
therefore momentum of ryfill would also be
1.75kg m/s
=> 1.75 =4 v
=> v = 0.4375 m/s
