As a sailboat sails 58.5 m due north, a breeze exerts a constant force F1 on the boats sails. This force is directed at an angle west of due north. A force of F2 of the same magnitude directed due north would do the same amount of work on a sail boat of work on the sailboat over adistance of just 38.5 m. What is the angle between the direction of the force F1 and due north?
