A spring with the Hooke's law constant k = 1 kg/s² has an oscillating object of mass 4kg attached to it. There is an external force F(t) = cos(wot) applied to the object and no damping force. Find the frequency wo of the external force F(t) which would yield a resonance, that is determine wo for which the equation the amplitude of the moving object increases without bound.
