Answer» :we have to FIND the recoil VELOCITY of gun.Solution :Mass of BULLET = 40gm = 0.04kgMass of Gun = 8kgvelocity of bullet = 800m/sAccording to conversation of momentum , momentum of bullet is equals to Momentum of Gun.As we KNOW that,Momentum of Bullet = 0.04 × 800⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 32 kg m/sLet the velocity of Gun is V.momentum of gun = 8v8v = 32v = 32/8v = 4━━━━━━━━━━━━━━━━━━━━━━━━━
