An object with mass 0.220 kg is acted on by an elastic restoring force with force constant 10.0 N/m. The object is set into oscillation with an initial potential energy of 0.140 J and an initial kinetic energy of 7.00×10−2 J.

a)What is the amplitude of oscillation?

b)What is the potential energy when the displacement is one-half the amplitude?

c)At what displacement are the kinetic and potential energies equal?

d)What is the value of the phase angle ϕ if the initial velocity is positive and the initial displacement is negative?
