thanks a lot! that really helped. next time ill try to not leave my physics book at school over the weekend

I think i am supposed to be finding it with respect to the earth, so I believe then the mass of the Earth is what is left

If F=mg, and Fc=Fg, Fc=mv2/r (thats v squared; my apologies, i have no idea how to use the superscript button), and Fg=Gm(1)m(2)/r2 (squared), where m(2) is the mass of, say, the earth, and m(1) is the mass of the object orbiting the earth. By substituting these equations together, we get...
