Chapter 3, Problem 4P

Three displacements are $\stackrel{\to }{A}$ = 200 m due south, $\stackrel{\to }{R}$ = 250 m due west, and $\stackrel{\to }{C}$ = 150 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.
