A cylinder of radius r and weight w with an initial counterclockwise angular velocity ω0 is placed in the corner formed by the floor and a vertical wall. The coefficient of kinetic friction between the cylinder and the wall and the floor is denoted by μk. Identify the correct expression for the time required for the cylinder to come to rest.
