## Homework Statement

A safe (mass = 1.00*10^3 kg) is suspended a height (d) above the top end of the spring (spring constant = 27800 N/m). The rope holding the safe breaks and the safe falls, compressing the spring a total distance of 1.80 m.

What is the initial height (d) of the safe when it was suspended above the spring?

## Homework Equations

F = ma

Fs = -kx

Fg = mg

## The Attempt at a Solution

I have only calculated Fg (9800N) and Fs (50,040N). I don't know where to go from here to get the height. Any help is appreciated, thank you.
