## Homework Statement

An astronaut in a rocket has an apparent weight of 1.35x10

^{3}N [down]. If the acceleration of a rocket is 14.7 m/s

^{2}[up] near Earth's surface, what is the astronaut's true weight? The acceleration due to gravity on Earth's surface is about 9.81 m/s

^{2}[down].

Mass of Earth is 5.97x10

^{24}, not sure if that's needed or not.

## Homework Equations

Fnet = ma

Fg = Gm

_{1}m

_{2}/ r

^{2}

g = Gm

_{(source)}/ r

^{2}

g = Fg / m

_{(test)}

## The Attempt at a Solution

I'm confused about what I should be solving for (I think it should be Fg), if the apparent weight is the normal force shouldn't it be directed up? I'm also confused about which acceleration to use and where, also which formula to use. So I'm pretty lost! Any help would be greatly appreciated :)
