Two blocks are placed at the ends of a horizontal massless board, as in the drawing. The board is kept from rotating and rests on a support that serves as an axis of rotation. The block on the right has a mass of 4.0 kg. Determine the magnitude of the angular acceleration when the system is allowed to rotate.
