Question

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

Answer 1

148.5 m

Explanation:

On earth initial velocity of baseball is
`u = sqrt(2gh) = sqrt(2 × 9.8 ms^-2 × 24.2 m) = 21.8 ms^-1`

If she throws the baseball with same velocity on moon,

The ball will the reach the height `= u^2/(2a) = (21.8 ms^-1)^2 / (2 × 1.6 ms^-2) = 148.5 m`
