Suppose you walk 18.0 m straight west and then 25.0 m straight north. (If you represent the two legs of the walk as vector displacements A and B, as in the figure below, then this problem asks you to find their sum R = A + B.) y A A + B = R R N B W E S A X How far, in meters, are you from your starting point? m What is the compass direction of a line connecting your starting point to your final position measured in degrees west of north?
