Fun Physics/Calculus Problem!

  1. Oct 13, 2011 #1
    Neglecting air resistance and the weight of the propellant, determine the work done in propelling a 13-ton satellite to a height of 300miles above earth and 550miles above earth.

    Assume earth has a radius of 4000miles.

    Can someone please show me how to do this?
