When a cannon fires a cannonball, the cannon will recoils backwards because:

• Energy if the cannonball and cannon is conserved

• Momentum of the cannonball and cannon is conserved

• Energy of the cannon is greater than the energy of the cannonball

• Momentum of the cannon is greater than the energy of the cannonball
