The wheel W of radius R is rolling without slip with angular speed ωW and angular acceleration αW. The bar AB has length 3R and is pinned to the outer edge of the wheel at A; the end B remains in contact with the surface. At the instant shown, determine the acceleration of point B. Express your answer in the component system shown.
