Homework Statement
A .2kg bouncy ball loses some of its kinetic energy when it collides with
the ground. Assuming it only maintains 90% of its energy after each bounce, how
high will it get for each of the first three bounces if it is initially launched
vertically at 15 m/s.
Homework Equations
KE = 1/2 mv^2
The Attempt at a Solution
KE(.9) = 1/2(.2)(15)^2
