Consider a bicycle wheel of mass M and radius R that sits on a flat, level surface, such that the surface is tangent to the wheel. One end of a spring (spring constant, k) is attached to bicycle wheel's hub, and the other end is fixed to a vertical wall. The spring is horizontal. There is sufficient friction to prevent the wheel from sliding at the point of contact with the surface. When the center of the wheel is directly...
