A uniform solid cylinder of mass m and radius R is set in rotation about its axis and lowered with the lateral surface on to the horizontal plane with initial centre of mass velocity v0 . If the coefficient of friction between the cylinder and the plane is n, find (a) how long the cylinder will move with sliding friction. (b) the total work done by the sliding friction force on the cylinder.

Solution:
A uniform solid cylinder of mass m and radius R is set in rotation about its axi
