The rotation of the 0.9-m arm OA about O is defined by the relation Eq. (1), where θ is expressed in radians and t in seconds. Collar B slides along the arm in such a way that its distance from O is Eq. (2), where r is expressed in meters and t in seconds. After the arm OA has rotated through 30°, determine the relative acceleration of the collar with respect to the arm (m/s^2).
