A rubber ball with a mass of 0.66 kg is released from rest from a height of 10 meters above the ground. Due to the interaction with the ground, each time it bounces it loses some of its total mechanical energy to non-conservative forces and it bounces to 68 percent of its height before it hit the ground. After 4 bounces, how much total energy is lost, in Joules?
