A gun (mass = M ) fires a bullet (mass = m ) with speed V r relative to the barrel of the gun which is inclined at an angle of 60 ° with horizontal. The gun is placed over a smooth horizontal surface. Find the recoil speed of the gun.

Question

A gun (mass = M ) fires a bullet (mass = m ) with speed V r relative to the barrel of the gun which is inclined at an angle of 60 ° with horizontal. The gun is placed over a smooth horizontal surface. Find the recoil speed of the gun., V = 1 2 mV r m + M, V = 1 2 mV r m - M, V = 1 2 MV r m + M, None of the above

Using conservation of linear momentum in the horizontal direction. m V r cos 60° - V = MV mV r cos 60 o m + M = V V = 1 2 mV r m + M
