Chapter 3, Problem 16PQ

Vector $\stackrel{\to }{A}$ has a magnitude of 4.50 m and makes an angle of 64.0° with the positive x axis. Vector $\stackrel{\to }{B}$, with a magnitude equal to that of vector $\stackrel{\to }{A}$, points along the negative y axis (Fig. P3.16). Graphically find the magnitude and direction of the resultant vector a. $\stackrel{\to }{A}+\stackrel{\to }{B}$, b. $\stackrel{\to }{A}-\stackrel{\to }{B}$, c. $\stackrel{\to }{B}-\stackrel{\to }{A}$, and d. $2\stackrel{\to }{A}-\stackrel{\to }{B}$.
