Consider a rubber ball which has an efficiency in one bounce of 34%. (That means 34% of the kinetic energy before the bounce remains kinetic energy after the bounce, while the rest of the energy is converted to thermal energy.) If the ball drops from a height of 7 m, then how high does it bounce back on the first bounce? Group of answer choices

9.4 m

7.0 m

4.6 m

1.9 m

2.4 m
