## Homework Statement

A downward force of 18.0 N must be applied to a woman weighing 480.0 N to keep her completely submerged in water. What is the density of her body

## Homework Equations

Density=m/v

Fb=density of fluid times volume of fluid times g

Fb=F(bottom) minus F(top)

## The Attempt at a Solution

Fb=F(bottom)-F(top)

480=18 minus f(top)

F(top)=-462 and we can't have it negative so idk what I am doing wrong. Also even if it was positive, I plug it in for F=mg to solve for m and then multiply it by the volume which does not get me the density answer please help me and explain the steps!
