Derivation of recoil of gun |
| Answer» Recoil velocity is the backward velocity experienced by a shooter when one shoots a bullet. Due to the recoil velocity the shooter experiences a backward jerk. The recoil velocity is the result of conservation of linear momentum of the system. In fact every projection system experiences a recoil velocity whether it is gun, crossbow, bow and arrow, rocket launchers.Initial momentum of the system including the gun and the bullet = 0Final momentum of the system = momentum of the gun + momentum of the bullet = Mv1+ mv (v is the recoil velocity of the gun)Applying conservation of linear momentum,0 = Mv1 + mvImplies, v1 = -(mv)/MThe negative sign indicates that the direction of velocity of the gun is opposite to the direction of velocity of the bullet. | |
