This question has THREE parts: (a), (b) and (c). B AB wwwwww The 13.9 kg slender rod AC is attached to a spring, which has a stiffness of 43 N/m and an unstretched length of 2.2 m. The rod is released from rest when 8 - 21. (Part b is worth Given AB = AC = 2.2 m, determine: (a) the angular acceleration (magnitude and direction) of rod AC when the rod is released from rest (ie, at the instant = 21"). Enter the magnitude of the angular acceleration of rod AC when the rod is released from rest (le, at the instant 0 = 21") below: (b) the magnitude of the reaction force at point A when 8 = 21". N AC Vo wwwwwwwww rad/s² Indicate the direction of the angular acceleration of rod AC when the rod is released from rest (ie, at the instant 0-21 on your handwritten solutions. (Part a is worth (Part c is worth (c) the magnitude of the angular velocity of rod AC when it reaches @ 81% rad/s
