How can a sailboat sail upwind? The wind exerts a force that is approximately perpendicular to the sail, as shown. The keel of the boat prevents it from sliding sideways through the water, such that the water exerts a force perpendicular to the long axis of the boat, as shown. The vector sum of these forces points in the direction that the boat will move. The wind is blowing from the north. The force on the sail is 200 N in a direction of [E 10° S]. The force on the keel is 188 N in a direction of [N 60° W]. Determine the vector sum (magnitude & direction) of these two forces and show that the boat will move upwind.
