Concept

Problem: A uniform bar has mass 30 kg and length 6.0 m. One of the bar is attached to a vertical wall by a frictionless hinge. A light horizontal cable connects the other end of the bar of the wall and holds the cable at an angle of 37° above the horizontal. If the cable is cut, what is the magnitude of the angular acceleration of the bar just after the cable is cut?
