Question

Do Exercise 3.16 again using analytical techniques and change the second leg of the walk to straight south. (This is equivalent to subtracting from A —that is, finding R' = A - 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 R'' = B - A. Is that consistent with your result?)

a) $R' = 38.0 \textrm{ m, } 54.2^\circ \textrm{ S of W}$

b) $R'' = 30.8 \textrm{ m, } 54.2^\circ textrm{ N of E}$
