A worker standing on a truck uses rope AB to slowly lower object B down a chute. The object weighs 100lb and fits loosely against the walls of the chute and slides with no friction. In the position shown, the center of object B is halfway down the chute. The person's hand A lies in the xy plane, and the chute lies in a plane parallel to the yz plane. (a) Determine the tension in rope AB and the reactions between the object and the chute. (b) If the worker wishes to slowly pull the object up the chute, explain how your answers to Part (a) change.
