A 3.0 kg wooden board is held in place by a rope on one end; the other end is held up by being in contact with a rough, vertical brick wall, as shown. The angles are as shown, and length of the board is 2.0m. Find the values of three forces: the tension in the rope, the normal force exerted by the wall on the board, and the friction force exerted by the wall on the board.
