1. The problem statement, all variables and given/known data Ball mass = 0.0027 kg PE (0.5 meters) = 0.01323 J height of ball after three trials = 0.19 meters KE before bounce = 0.01323 J PE at new max height = 0.00503 Total energy = KE + PE Ke after bounce = ? 2. Relevant equations mgh 3. The attempt at a solution I did a lab where I bounced a ball at a certain height. I found the potential energy with the equation mgh (m = 0.0027 g, g=9.8, h=0.5m), so it is 0.01323J. I am supposed to find the kinetic energy before the ball bounced (I think it's equal to the PE that I calculated), and I'm supposed to find the PE at the maximum height the ball hit (h = 0.19 m), so when I plug it into the mgh equation, I get 0.00503J. I know the total energy would be KE before the bounce + PE at the maximum height, which was 0.00503J, so I just add those up. How do I find the KE after the ball bounced?
