Greg is walking in a daze. He first walks 1000m NE. Then he walks 3000m S and finally 2200m 20° N of E. How far away did Greg end up from the starting point and in which direction?
I would change the NE to a N component, and an E component.
I then would add all the distances to get a final N,E directions.
Then add those vectors back into a single vector.
