The two pulleys are riveted together to form a single rigid unit, and each of the two cables is securely wrapped around its respective pulley. If point A on the hoisting cable has a velocity v = 0.9 m/s, determine the magnitudes of the velocity of point O and the velocity of point B on the larger pulley for the position shown.
