The wind exerts a force of 500N, South on a sailboat, while the water exerts a force of100N East on the sailboat.

Net force = 509.90 N

Explanation:

Given that,

Force exerted by wind is 500 N South on a sailboat.

The force exerted by water is 100 N on the sailboat.

Two forces are acting at an angle of 90 degrees. We can find the net force acting on the sailboat. Let it is F.

So, the net force on the sailboat is 509.90 N.
