On planet Zog, Mr. Spock measures that it takes 1.44 s for a mass of 0.3 kg to hit the ground when released from rest from a height of 2.73 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.

So, you would set up two equations and set them equal to each other...first you would have to find the amount of time it would take the mass to fall on earth...then set the equation from earth with the found time against the equation from planet Zog with its gravity as the only variable.
I'll figure it out and give you more of an answer.
alright...ready?
I was stupid...just use this equation:
Y = Yo + Vo t + .5 a t^2
where Y is the final height (zero), Yo is the initial height, Vo is the initial velocity (zero), a is the acceleration of gravity on the planet Zog, and t is the time it takes for the mass to hit the ground.

Ask your teacher. Don't make us do your homework for you. :-P
