A cannon launches a 4.0kg bowling ball with 50J of kinetic energy what is the bowling ball's speed

In each case the momentum before the collision is: (2.00 kg) (2.00 m/s) = 4.00 kg * m/s 1. In each of the three cases above show that momentum is conserved by finding the total momentum after the collision. 2.
