Question

The acceleration due to gravity on the moon
is about one-sixth its value on earth.
If a baseball reaches a height of 50 m when
thrown upward by someone on the earth,
what height would it reach when thrown in
the same way on the surface of the moon?
Answer in units of m.

Answer 1

the K.E. of the ball becomes P.E. at its peak

1/2 m v^2 = m g h

the only difference on the moon is that g is 1/6 of Earth

so h will be six times the Earth value
