Question1

A rock is projected upward from surface of the moon, at time t = 0.0 s, with a velocity of 30 m/s.

The acceleration because of gravity at surface of the moon is 1.62 m/s^2

What is an average velocity of the rock during first 22.0 s of flight

Question2

A ball is thrown straight upward from the surface of the moon. Is the maximum height it reaches less than, equal to, or greater than highest height reached by a ball thrown upward on earth with the similar initial speed? (Ignore air resistance in both cases) explain.
