If a ship goes 6N North, but gets pushed 7N Eastward by wind, what's the magnitude and direction of the Resultant Force.

So you would draw it down first. Then from the starting point, link it with the end point, to make a trinngle. Now you would do Pythagoras. [c²=a²+b²] Your a and b would be 6 and 7. Follow the formula and you would get 9.2N North East
