A basketball player runs down the court, following the path indicated by the vectors A, B , and C in Figure 3-43 . The magnitudes of these three vectors are A=10.0 m, B=20.0 m, and C=7.0 m. Find the magnitude and direction of the net displacement of the player using (a) the graphical method and (b) the component method of vector addition. Compare your results.
