**drwls**, Thursday, March 12, 2009 at 11:48pmLet r be the fraction of kinetic energy left after a single bounce. Thatequals the height ratio for each pair of successive bounces, which is proportional to the recovered kinetic energy ratio. The ratio is called the coefficient of restitution.

H (after fifth bounce)/Ho = r^5 = 0.76/5 = 0.152

r = (0.152)^0.2 = 0.686
