Rod AB is attached to collars at its ends by using ball-andsocket joints. If collar A moves along the fixed rod with a velocity of v_A = 5 m/s and has an acceleration a_A = 2 m/s² at the instant shown, determine the angular acceleration of the rod and the acceleration of collar B at this instant. Assume that the rod’s angular velocity and angular acceleration are directed perpendicular to the axis of the rod.
