A 2.40 kg object is hanging from the end of a vertical spring. The spring constant is 41.0 N/m. The object is pulled 0.200 m downward and released from rest. Complete the table below by calculating the translational kinetic energy, the gravitational potential energy, the elastic potential energy, and the total mechanical energy E for each of the vertical positions indicated. The vertical positions h indicate distances above the point of release, where h = 0.(adsbygoogle = window.adsbygoogle || []).push({});

h (m) KE (J) PE-gravity (J) PE-elastic (J) E (J)

0

0.200

0.400

I know how to get PE-Gravity, mgh. And i know Trans kinetic= 1/2mv^2 but im having trouble coming up with V^2.

And with PE elastic= 1/2kx^2 but i cant get the correct number for x. Is x the I-.200 plus h
