Homework Statement
Ned climbs to the peak of Mt. Everest, the tallest peak on Earth at 8850 m above sea level. Ned's mass is 95 kg, the mass of Earth is 5.98 x 1024 kg, and Earth's radius is 6.37 x 106 m. What is the difference in Ned's weight when comparing his weight at the top of the mountain to his weight at sea level?
Homework Equations
Fg = Gm1m2 / r2
g = Gm / r2
g = Fg / m
The Attempt at a Solution
I think I have the field strength equal to 9.80 N using the equation g = Gm / r2 . After that I'm lost, I have no idea how to get his weight at the top of the mountain!
