A point mass m under no external forces is attached to a weightless cord fixed to a cylinder of radius R (which is also fixed). Initially, the cord is completely wound up so that the mass touches the cylinder. A radially directed impulse is now given to the mass, which starts unwinding.
(a) Find the Lagrangian in terms of the coordinate ϕ.
Homework Answers
Since lagrangian = T-V
And it is given that no force is acting this implies that
potential energy V =0 and hence the lagrangian contains only T
term.

Consider a bicycle wheel that initially is not rotating. A block of mass m is attached to the wheel via a string and is allowed to fall a distance h. Assume that the wheel has a moment of inertia I about its rotation axis Now consider the case that the string tied to the block is wrapped around a smaller inside axle of the wheel of radius rB as shown in (Figure 2) . Find ωB, the angular speed of...
