The wind exerts a force of 452 N north on a sailboat, while the water exerts a force of 325 N west on the sailboat. What is the magnitude and direction of the net force on the sailboat?
Magnitude = 557 N
In this question you have a force (452N) due North and a force (325N) due West. Since these directions are
To calculate the magnitude you must reach WAAAAAY back in your math classes to the pythagorean theorem; since you can view these vectors as a triangle with the net force being the hypotenuse.
You can then take the square root of your answer to find the magnitude in Newtons.
