The system in the figure below consists of a massless spring with stiffness 60 N/m and
unstretched length 0.4 m (indicated in black in the figure) that is wrapped around a
rigid massless bar (indicated in red in the figure). A mass of 5 kg is attached to the end
of the spring and slides without friction along the bar. The spring/bar assemblage
pivots without friction about the point O. Take as generalised coordinate q the angle
of the bar w.r.t. the vertical and as generalised coordinate q2 the stretch of the spring.
