1. The problem statement, all variables and given/known data An astronaut weighs 800 N on the surface of the Earth. What is the weight of the astronaut 6.37*10^6 km above the surface of the earth? 2. Relevant equations F = G (m1)(m2)/(d)^2 W=ma 3. The attempt at a solution I am sure that I need the previous equations I listed, although I am not quite sure how to actually solve this problem. A solution to this type of problem would be most appreciated. Thanks!
