For an Ideal spring...At half Amplitude, what % of the energy is kinetic?(adsbygoogle = window.adsbygoogle || []).push({});

I know at A the kinetic energy it instantly zero which makes max potential energy (.5kx^2)

I also know that after released, at the instant passising through the equilibrium point kinetic energy is max and potential energy is zero.

From the energy conservation approach Et = Ei so, .5mv^2 = .5kA^2

I have no clue where to start this problem. Maybe I am making it too difficult
