On planet Zog, Mr. Spock measures that it takes 1.47 s for a mass of 0.50 kg to hit the ground when released from rest from a height of 2.85 m. Calculate the size of the acceleration of gravity on that planet. He decides to repeat the experiment. Calculate the work he must do to move the mass from the ground back up to its initial height.
