The moon's gravity is about one sixth of the Earth's. (Basically, one sixth of 9.80m/s^2). If two objects were dropped at the same height on the Earth and on the Moon, the time it would take for the object to reach the surface of the moon compared to the Earth is...(adsbygoogle = window.adsbygoogle || []).push({});

a) 6

b) 36

c) Square root of 6

I can't figure it out. I tried using the formula:

v^2 = -2g(Yo-Y)

but i got some really weird answers. Any help please? :S
