A cylinder of mass M=58 kg, radius R=1.3 m and moment of inertia I=(1/2)MR2 is initially rotating around its central axis with an angular velocity ωi= 1.8 rad/s. A tangential force F of constant magnitude applied to the edge of the cylinder during 5.9 s brings it to rest. What is the magnitude of the force F?
