Question
The figure below shows the horizontal forces acting on a sailboat moving north at constant velocity, seen from a point straight above its mast. At the particular speed of the sailboat, the water exerts a drag force on its hull and theta = 42. 5 degree . For each of the situations (a) and (b) described below, write two component equations representing Newton's second law. Then solve the equations for P (the force exerted by the wind on the sail) and for n (the force exerted by the water on the keel). Choose the x direction as east and the y direction as north. Now choose the x direction as Q = 42. 5 degree north of east and the y direction as theta = 42. 5 degree west of north. Compare your solutions to part (a) and (b). Do the results agree?Explanation / Answer
a) n = 166.97 N p = 226.47 N b) n= 166.97 N p= 226.47 N c) yes ,results agree
