A 5.000kg mass starts from rest and slides down on an inclined plane, hits a bumper at the bottom of the inclined plane and bounces back up the inclined plane and comes to rest again. Through the collision with the bumper, 0.700J of energy is lost. The mass started at a height of 0.250m above the bumper and rebounded to a height of 0.210m after the collision. How much energy was lost in from when the mass started at rest until it rebounded to its maximum height after the collision?
