1. The problem statement, all variables and given/known data A tennis ball and basketball are dropped from a height of 1m (the tennis ball on top of the basketball). The tennis ball has a mass of 75g and the basketball has a mass of 1kg. When dropped separately, the tennis ball bounces to a height of 0.5m and the basketball to a height of 0.8. Find the max height of the tennis ball when the balls are dropped together if the basketball's velocity after the bounce is 1m/s. Use g=10m/s/s 2. Relevant equations p=mv U=mgh K=0.5mv^2 p1=p2 E1=E2 v^2=v0^2+2gh 3. The attempt at a solution I tried to do standard conservation of momentum and conservation of energy, but realized I needed to account for energy loss. That is where I got lost. How do you account for energy loss and/or what is the answer so I can check my work when I'm done?
