If a ball bounces 2/3 of its previous height each time it bounces, how high will the ball bounce after the fifth bounce if the ball is dropped from 20 feet?
----------------
h = 20*(2/3)^5 = 20*(32/243)
h = ~ 2.634 feet
-----------------
This is similar to the physics term "coefficient of restitution"
The COR for this example is sqrt%282%2F3%29
