The potential energy of a simple harmonic oscillator, when the particle is half way to its end pint is

The potential energy of a simple harmonic oscillator of mass 2 kg at its mean position is 5 J. If its total energy is 9 J and amplitude is 1 cm, then its time period is

If the potential energy of a harmonic oscillator of mass 2kg on its equilbrium position is 5 joules and the total energy is 9 joules when the amplitude is one meter the period of the oscillator ("in" sec) is-
