1. Is bodychecking someone an elastic or inelastic collision? Why? Explain with details.

2. Come up with a realistic word problem of Person 1 (mass: 87 pounds) running Person 2 (60 pounds) and bodychecking them. Come up with your own numbers, such as speed. Calculate the total momentum before the collision, total momentum after the collision, type of energy transferred, total energy before the collision, and total energy after the collision.
