## 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 / r

^{2}

g = Gm / r

^{2}

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 / r

^{2}. After that I'm lost, I have no idea how to get his weight at the top of the mountain!
