A 10.0 kg mass is at rest on a board inclined at an angle of 30.0o above the horizontal. The mass is held in place by the combination of static friction and the 10.6 N tension in a cord attached to the mass on the uphill side, and running parallel to the board. Find the coefficient of static friction (s) between the mass and the board.
