A golf ball is dropped from a 50 meter tall building. These suckers are quite bouncy... but not perfectly bouncy. Your buddy notices that on its first bounce, it reaches 46 meters hign. Cleany this bail is losing energy to friction in the collision with the ground. Find the fraction of the total initial energy friction stole from the ball as it bounced in a slightly inelastic manner. Or in other words, E Eo (Note: A fraction of 0 indicates a perfectly elastic bounce, meaning no energy is "lost" to friction. A fraction of 1 indicates a perfectly inelastic bounce, meaning ALL the energy went into friction stuff. This golf ball is quite bouncy, so expect an answer closer to 0 than 1.) 0.25 0.08 0.04 0.15
