The rotation of the 0.9-m arm OA about O is defined by the relation 0 = 0.15t2, where 0 is expressed in radians and t in seconds. A 0.75-kg collar B slides along the arm in such way that its distance from O is r= 0.9 – 0.12t², expressed in meters and t in seconds. Determine the magnitude and direction of %3D where r is II the resultant force on collar B after the arm OA has rotated 30°.
