By Applying Law of conservation of momentum,
= M1V1 = M2V2
4 * V1 = 0.01 * 400
4 * V1 = 4
V1 = 1
Recoil velocity of the gun = 1 m/s.
Hope this helps!

Initial momentum = 0
Final momentum = 0.01*400 + 4v
Momentum is conserved
0 = 4 + 4v
v = -1 m/s
(-ve becuase gun moves in opposite direction of bullet)
Recoil velocity of gun is 1 m/s
