6. The acceleration due to gravity on the surface of the Moon is only 17% of that on the surface of the Earth. If a person can throw a heavy ball 10.0 m vertically upward on Earth, how high could she throw it on the Moon if she gives it the same starting speed? How much longer would it be in motion (up and down) on the Moon compared to on the Earth? A
