A man has a mass of 80kg on the Earth's surface.

Question

Part A
How far above the surface of the Earth would he have to go to "lose" 13% of his body weight?

Answer 1

weight= forcegravity=GMeM/r^2

So I see this relationship:

.87=(radiusearth/(radiusEarth+height))^2

solve for height

Answer 2
