One-dimensional Gravitational motion

  1. Sep 16, 2009 #1
    A) It takes 2.80 s for a small ball with a mass of 0.040 kg released from rest from a tall building to reach the ground. Calculate the height from which the ball is released.

    B)If that ball had been released from the same height, but this time above the surface of the moon, how long would it have taken for the ball to hit the ground?

    Hi nycjay222,
    Welcome to PF.
    How much you know about the free fall?
    Can you find out the relevant equations for free fall?
