Marble B travels down the hollow tube with a velocity relative to the slot of  v_Bxyz=2deltadelta.deltadelta mm/s and a_Bxyz = -deltadelta.deltadelta mm/s².  The angular velocity of the slotted member are omega=delta.deltadeltadelat rad/s and alpha=.deltadeltadeltadelta rad/sec².  Find the absolute acceleration of the marble B.
