(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 293g block is placed on a spring with a spring constant of 161N/m, compressing it 42cm. What height does the block reach when it is launched?

2. Relevant equations

Eel=1/2*k*x^{2}

Eg=mgh

3. The attempt at a solution

Eg=.293*10*.42=1.2306

1.2306=1/2*161*x^{2}

1.2306=80.5x^{2}

.0153=x^{2}

.1236=x

Did I make any mistakes? Because I cant get it right.
