I think you mean e = KE(ball) / PE(bricks) since this will result in a percentage and not be greater than zero. But thanks, I can use the second law of thermodynamics and show which setup is best. This is the averaged data. Empirically it shows that less mass is more efficient and a hanging...

In my physics problem I want to see how the energy transferred to a projectile differs if I (Setup A) set the weight on the lever arm and (Setup B) have a hanging weight on the lever arm. Here are some images that better describe my project: My experiment consisted of a base made of a...
