Use the law of conservation of momentum. The bullet and the gun will have equal and opposite momenta right after the bullet leaves the rifle.
2.0 * Vrecoil = 0.05 kg * 200 m/s
Solve for Vrecoil
2.0 * Vrecoil = 0.05 kg * 200 m/s
Solve for Vrecoil

commanly the formula is: *m1u1+m2u2+m1v1+m2v2*
substitute the values according to this formulae.
This data can be likely:
mass of rifle=m1=2.0kg
mass of bullet=m2=50g=kg= 50/1000=0.05kg
velocity of gun=v1=0m/s
velocity of recoil of gun=v2=?
substitute the values according to this formulae.
