1. The problem statement, all variables and given/known data What is the approximate value of the gravitational force between a 61 kg astronaut and a 71000 kg space shuttle when they're 81 m apart? 2. Relevant equations F = [G(Mm)/r^2] 3. The attempt at a solution F = (6.67×10−11 N·m2/kg2)(61 kg)(71,000 kg)÷ (84 m)2 = 48.4 nN. Web assign marked it wrong? Is it wrong?
