16-31. Determine the distance the load W is lifted in t = 5 s using the hoist.The shaft of the motor M turns with an angular velocity v = 100(4 + t) rad>s, where t is in seconds.
16-33. The driving belt is twisted so that pulley B rotates in the opposite direction to that of drive wheel A. If the angular displacement of A is uA = (5t3 + 10t2) rad, where t is in seconds, determine the angular velocity and angular acceleration of B when t = 3 s.
