Chapter 3, Problem 12P

Three displacements are $\stackrel{\to }{A}=200\text{m}$ due south, $\stackrel{\to }{B}=250\text{m}$ due west, and $\stackrel{\to }{C}=150\text{m}$ at 30.0° east of north. (a) Construct a separate diagram for each of the following possible ways of adding these vectors: ${\stackrel{\to }{R}}_1=\stackrel{\to }{A}+\stackrel{\to }{B}+\stackrel{\to }{C};{\stackrel{\to }{R}}_2=\stackrel{\to }{B}+\stackrel{\to }{C}+\stackrel{\to }{A};{\stackrel{\to }{R}}_3=\stackrel{\to }{C}+\stackrel{\to }{B}+\stackrel{\to }{A}$. (b) Explain what you can conclude from comparing the diagrams.
