5. How can a sailboat sail upwind? The windexerts a force that is approximatelyperpendicular to the sail, as shown. The keelof the boat prevents it from sliding sidewaysthrough the water, such that the water exerts aforce perpendicular to the long axis of the boat,as shown. The vector sum of these forcesWindpoints in the direction that the boat will move.Force onThe wind is blowing from the north. The force the keelon the sail is 200 N in a direction of [E 10° S].The force on the keel is 188 N in a directionof [N 60° W].Force omthe sailDetermine the vector sum (magnitude &direction) of these two forces and show thatthe boat will move upwind.
