What is the total momentum of cannon and shell before and after firing?
Before the cannon is fired, the momentum is zero. So, after firing, the momentum must still be zero. The momentum of the shell is equal and opposite to that of the cannon, because there is an action and an equal reaction force. Since the momentum difference must be equal: (mv)cannon = (mv)shell Thus, (mv)c - (mv)s = 0 A simple way of looking at it is this is: If the shell is 100 times lighter than the cannon then the shell will move off 100 times faster than the cannon recoils. Remember that, in explosions, the lighter portion moves off faster than the heavier one.
