1. AllTehMaffs Group Title

$R=3.2R_E$ $g=G\frac{M_E}{(3.2R_E)^2}$

2. AllTehMaffs Group Title

RE = radius of the earth ME = mass of teh erf

3. hhuumm Group Title

so the radius of the earth is supposed to be a known thing?

4. AllTehMaffs Group Title

yes. Both the mass and radius of the earth are known quantities. It should be either in your text book or google it.
