1. The problem statement, all variables and given/known data If a person has a mass of 68kg, how much does he weigh on the top of mount everest (8488km above sea level? Given: m=68kg, d=8488m 2. Relevant equations F = (G(m1)(m2)) / r^2 3. The attempt at a solution I tried figuring out the new radius. Once i get the radius i enter all the data and rearrange the formula to get m2 by itself. Fr^2/Gm1 = m2 My problem is getting the new radius.
