Chapter 3, Problem 19PE

Do Exercise 3.16 again using analytical techniques and change the second leg of the walk to 25.0 m straight south. (This is equivalent to subtracting B from A —that is, finding $\text{R}\text{'}=\text{A}-\text{B}$ ) (b) Repeat again, but now you first walk 25.0 m north and then 18.0 m east. (This is equivalent to subtract A from B —that is, to find $\text{A}=\text{B}+\text{C}$. Is that consistent with your result?)
