Vector Addition

Since many of you seem a little uncertain about adding vectors, here's a quick review example:



The proceedure is the same when you have more than two vectors. Break down all the vectors into components relative to some coordinate system (note that you can choose this such that it is aligned with one of your vectors), add all the components and then using the pythagorean theorem find the magnitude of the resultant vector, and find the angle using trigonometry.
