The rate of the rotating arm is 4 rad/s when it is 3 rad/s and 0 = 180'. Determine the force it must exert on the 0.89 kg smooth cylinder if it is confined to move along the slotted path. Motion occurs in the horizontal plane. Round your answer to 2 decimal places. 0 = 4 rad/s, 0 = 3 rad/$2 0 = 180 D N m
