Question: 1 . A ball is dropped from rest and falls to the floor. The inital gravitational potentlal energy of the ball - Earth - floor

1. A ball is dropped from rest and falls to the floor. The inital gravitational potentlal energy of the ball-Earth-floor
system Is 10 J. When the ball comes In contact with the ground, some energy is lost in the form of thermal energy.
The ball then bounces back up to a helght where the gravitational potential energy is 7 J. What was the mechanical
energy ol the ball-Earth
-1loor system the instant the bal let the floor?
