1. The problem statement, all variables and given/known data
Using the definition of gravity, derive the mass of the Earth 2. Relevant equations I am unsure if this is simply a plug n chug problem and I am over thinking it or there is some way to use calculus to derive the mass from the gravity equation. 3. The attempt at a solution I am looking at the equation a=GM(earth)/r^2 I know I can simply find these values in my text book, but I dont see why it would be that simple of a problem. So I just feel like there must be something I am missing.

I don't think you're missing anything. Plugnchug away!
