An extremely elastic ball loses only 20 percent of its kinetic energy in a bounce. If such a ball were dropped from a height of 5.0 m, how high would the ball bounce? 1.0 m 2.0 m 4.0 m 5.0 m Any help is really appreciated! :)

I believe the answer is 4.0, because 0.2 * 5 = 1.0. Then, 5.0 - 1.0 = 4.0
