Problem
A crate of mass 8 kg is attached to a movable (single) pulley. One end of an ideal rope is fixed to the ceiling; the rope passes under the pulley attached to the crate and then upward where a worker pulls on the free end with a steady force of 40 N. Neglect friction.
(a) Calculate the magnitude of the tension in the rope.
(b) Determine the magnitude and direction of the acceleration of the crate.
