SUMMARY
The equation for momentum in a rifle firing a bullet is derived from the conservation of momentum principle. When a rifle of mass M fires a bullet of mass m at velocity v, the resulting velocity of the rifle (V) can be expressed as V = -mv/M. This indicates that the rifle recoils in the opposite direction to the bullet's motion, maintaining the system's overall momentum. The discussion confirms the accuracy of this equation and encourages further questions within the same thread.
