A collar of mass m which slides on a frictionless horizontal rod is attached to a spring

Question:

A collar of mass m which slides on a frictionless horizontal rod is attached to a spring of constant k and is acted upon by a periodic force of magnitude P = Pm sin ωft. Determine the range of values of ωf for which the amplitude of the vibration exceeds three times the static deflection caused by a constant force of magnitude Pm.
