Consider the system formed by the tapered-type flywheel and the 100-kg block shown in the figure below. The block is suspended from an inextensible cord that is wrapped around a pulley of 300-mm radius rigidly attached to the flywheel. The pulley and the flywheel have a combined mass moment of inertia about its center of IT= 0.45 kg. m2. At the instant shown, the velocity of the block is 2 m/s directed downward. If the bearing at O is poorly lubricated and that the bearing friction is equivalent to a couple moment M of magnitude 80 N.m, determine the velocity of the block after it has moved 1 m downward.

Consider the system formed by the tapered-type flywheel and the 100-kg block shown in the figure below. The block is suspended from an inextensible cord that is wrapped around a pulley of 300-mm radius rigidly attached to the flywheel. The pulley and the flywheel have a combined mass moment of inertia about its center of IT= 0.45 kg. m2. At the instant shown, the velocity of the block is 2 m/s directed downward. If the bearing at O is poorly lubricated and that the bearing friction is equivalent to a couple moment M of magnitude 80 N.m, determine the velocity of the block after it has moved 1 m
