## Homework Statement

A block of mass m = 2.0 kg is dropped from height h = 55 cm onto a spring of spring constant k = 1960 N/m (Fig. 8-36). Find the maximum distance the spring is compressed.

## Homework Equations

PEspring=1/2 kx

^{2}F=-kx PE gravity=mgh KE gravity=1/2mv

^{2}

## The Attempt at a Solution

I started by setting PE gravity equal to PE spring so that mgh=1/2kx

^{2}.

so then I had (2)(9.8)(.55+x)=(1/2)(1960)((.55+x)^2)

I then solved for x and got x=.55 but this was wrong-why?
