Thanks aim! I got the correct velocity using your method, but i don't figure out the distanse as a function of time... Could you please try to explain it again, a bit more detailed? :)

Homework Statement An object is dropped from a distanse of 2*R(moon radius) from moon senter. How many seconds does it take until impact with moon, and in what speed will it hit? The distanse of the fall will be 1.74*10^6 m. The problem is the not so constant acceleration.. ;) gravity...
