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

Use the energy integral lemma to show that motions of the free undamped mass-spring oscillator my"+ky=0 objey

m(y')^2 = ky^2=constant

2. Relevant equations

E(t)=1/2 y'(t)^2 - F (y(t))

3. The attempt at a solution

I am not sure how to even start this problem.I would like to know just what the problem is asking for.I do not have a problem doing the math to it.

Thank you
