A cylinder of mass M, radius r, is set to rotate with angular velocity ω0 about its own axis, which is fixed. If after time t the angular velocity is ω1, find the frictional torque N on the cylinder at time t, assuming that: (a) N is constant, (b) N is proportional to ω, the instantaneous angular velocity

A uniform disk of radius 0.529 m and unknown mass is constrained to rotate about a perpendicular axis through its center. A ring with same mass as the disk\'s is attached around the disk\'s rim. A tangential force of 0.223 N applied at the rim causes an angular acceleration of 0.103 rad/s2. Find the mass of the disk.
