As a sailboat sails 51.5 m due north, a breeze exerts a constant force 1 on the boat's sails. This force is directed at an angle west of due north. A force 2 of the same magnitude directed due north would do the same amount of work on the sailboat over a distance of just 41.5 m. What is the angle between the direction of the force 1 and due north?
