having trouble with this problem... any ideas?(adsbygoogle = window.adsbygoogle || []).push({});

A 2.798-kg block is on a horizontal surface with muk = 0.170, and is in contact with a lightweight spring with a spring constant of 775 N/m which is compressed. Upon release, the spring does 0.969 J of work on the mass while returning to its equilibrium position. Calculate the distance the spring was compressed. What is the velocity of the mass as it breaks contact with the spring?

i need this equation: 1/2 kx^2 ... but i'm not sure where to go from here...
