Question

The fastest pitch ever thrown was 105 mph, or 47 m/s. Wow! The moon's gravity is 16.7% that of earth. If this pitcher threw the ball straight up on earth, it would reach a height of 112.59 meters. How high would it go on the moon? This is a conversation

of energy program. Kinetic energy = Potential energy.

Answer 1

PE = M G H potential energy

PE(Earth) = PE(Moon)

9.80 He = 9.80 * .167 Hm omitting M which is same on both sides

Hm = 9.80 * 112.59 m / (.167 * 9.80) = 112.59 m / .167

Height (Moon) = 674 m
