Document Summary
When two vectors are added graphically, the second vector is positioned with its tail at the tip of the first vector. The resultant then runs from the tail of the first vector to the tip of the second vector. In this case, vector will be positioned with its tail at the origin and its tip at the point (0, 29). The resultant is then drawn, starting at the origin (tail of first vector) and going 14 units in the negative y-direction to the point (0, 14). , must then start from the tip of at point (0, 29) and end on the tip of at point (0, 14) as shown in the sketch at the right. The distance d from a to c is where and (b) (c) Thus, the answer computed above is only approximately correct. Choose the positive x-direction to be eastward and positive y as northward.
