1. The problem statement, all variables and given/known data A space vehicle of mass 555kg, experiences a gravitational pull from Earth of 255N. The mass of Earth is 5.98x10 (to the power of 24) kg.How far is the vehicle a) from the center of the Earth, and b) above the surface of the Earth? 2. Relevant equations FG = GM1M2/d squared 3. The attempt at a solution I rearranged the equation above, and solved for d (the radius) and got the answer 2.95x10(to the power of 7) m, which I believe is correct. However, I can't seem to figure out how to find part b) or even what variable I am solving for. I'm not solving for the radius because I already did that in a) so I think I'll have to alter the equation somehow. Any help would be greatly appreciated!
