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 F vector = 194-N drag force on its hull and Theta = 49.0 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 Theta = 49.0 degree north of east and the y direction as Theta = 49.0 degree west of north.

Explanation / Answer

P* sin(49) = F

P = 257.052N

P*cos(49) =N

N = 168.641N

b) The answer remains the same. the forces doesnt change based on the selection of axis.
