I was trying to work on this for a little but couldn't figure it out.(adsbygoogle = window.adsbygoogle || []).push({});

A. A spring with a spring constant k=30 N/m is compressed and latched at 0.10 m. How much elastic potential energy is stored in the spring?

??? 0.15 J

B. An object with a mass of 5.0 kg is placed next to the spring and the spring is unlatched. Neglecting the mass of the spring, what is the final kinetic energy of the object?

I know that Ek=1/2 mv(squared)

Could someone help me??
