1. The problem statement, all variables and given/known data A 92 kg man weighs 189 Newtons on the surface of an unknown planet. What ist he acceleration of gravity on this planet? Basically, I thought the formula to finding the gravitational force was G(gm)/r^2, but I'm missing the distance that the man from the planets center is. I don't know where the 189 newtons fit in. 2. Relevant equations G = (gm)/r^2 3. The attempt at a solution G = (gm)/r^2 G = (6.67x10^-11nm^2/kg^2)(92kg)/r? What is R? I'm totally lost. Thank you, appreciate it!
