As a sailboat sails 53.0 m due north, abreeze exerts a constant force F1 onthe boat's sails. This force is directed at an angle west of duenorth. A force F2 of the same magnitudedirected due north would do the same amount of work on the sailboatover a distance of just 36.5 m. What is the angle between the direction of the forceF1 and due north?
