When the displacement of a mass on a spring is 12a the half of the amplitude, what fraction of the mechanical energy is kinetic energy? at what displacement, as a fraction of a, is the mechanical energy half kinetic and half potential?

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
