Several rods are brazed together to form the robotic guide arm shown that is attached to a ball-and-socket joint at O. Rod OA slides in a straight inclined slot, while rod OB slides in a slot parallel to the z axis. Knowing that at the instant shown vB = (9 in./s)k, determine (a) the angular velocity of the guide arm, (b) the velocity of point A, (c) the velocity of point C.
