A ball is dropped from 1.5 m and rebounds to 1.2m. How many times will it bounce before losing 90% of it's energy? I assumed energy was hight times gravity so when the rebound was only 10% of the original amount, 90% of the energy is lost. Is this the correct idea? I calculated 10 bounces resulted in a bounce hight of .16m.
