On the moon, the acceleration due to gravity is only 1.6 m/s/s. If someone on earth can throw a baseball 24.2 m high, how high could he throw it on the moon?

Answer 1

V^2 = V1^2 + 2g*h = 0 @ max ht.
Vo^2 = -2g*h = 19.6*24.2 = 474.32
Vo = 21.8 m/s = Initial velocity.

h = (V^2-Vo^2)/2g = (0-(21.8^2)/-3.2 =
148.3 m.
