Question

A uniform cylinder with a mass M and a radius R is mounted on a stationary, horizontal
axis. A massless cord wrapped around the cylinder is attached to a block with a mass m that
slides on a horizontal surface. The coef?cient of kinetic friction between the horizontal surface
and the mass m is k. A horizontal force F is applied to the mass m and pulls it a distance L. Express your answers in terms of M, R, m, k, F and L.
Using energy considerations, calculate the velocity of the mass m after it has been pulled
a distance L.
