## Homework Statement

Find the Linear momentum of an unwinding Cylinder with one end of a string attached to the ceiling. The mass of the cylinder is m and radius r. The cylinder is uniform and there is no slipping.

## Homework Equations

Momentum, P = mv

moment of inertia , I = 1/2 MR^2

## The Attempt at a Solution

distance from ceiling to point on cylinder , y = l(length of string unwound)

so is the momentum simply m*dl(t)/dt?
