## Homework Statement

At what altitude above the Earth's Surface would your weight be half of what it is at the earth's surface?

and I know that the mass of the earth is 5.974 X 10^24 and the Radius of the earth is 6.371 X 10^6

## Homework Equations

I know that F = GM1M2 / R^2

## The Attempt at a Solution

Ok so I was sitting in class and I sort of remember him changing the formula to this

G = Me * M / R^2

so and I think I am going this correctly I am thinking that

G = Me * 1/2M / R^2 + h = G = Me * M / R^2

I think that is right but I am not sure, my professor is a nice guy but he confuses me a lot. I just don't know what to do after this it has been years since I had a math class. Can anyone help?
