2. A hawser thrown from a ship to a pier is wrapped two full turns around a capstan. The tension in the hawser is 7500 N; by exerting a force of 150 N on its free end, a dock worker can just keep the hawser from sliding. (a) Determine the coefficient of friction between the hawser and the capstan. (b) Determine the tension in the hawser that could be resisted by the 150 N force if the hawser were wrapped three full turns around the capstan.
