Chapter 3, Problem 6P

(II) Figure 3–36 shows two vectors, $\stackrel{\to }{A}$ and $\stackrel{\to }{B}$. whose magnitudes arc A = 6.8 units and B = 5.5 units. Determine $\stackrel{\to }{C}$ if (а) $\stackrel{\to }{C}=\stackrel{\to }{A}+\stackrel{\to }{B}$, (b) $\stackrel{\to }{C}=\stackrel{\to }{A}-\stackrel{\to }{B}$, (с) $\stackrel{\to }{C}=\stackrel{\to }{B}-\stackrel{\to }{A}$. Give the magnitude and direction for each.
