Question

(a) Repeat the problem two problems prior, but for the second leg you walk 20.0 m in a direction $40.0^\circ$ north of east (which is equivalent to subtracting B from A — that is, to finding R' = A - B).

(b) Repeat the problem two problems prior, but now you first walk 20.0 m in a direction $40.0^\circ$ south of west and then 12.0 m in a direction $20.0^\circ$ east of south (which is equivalent to subtracting A from B — that is, to finding R'' = B - A = - R'). Show that this is the case.

a) $26.6 \textrm{ m, } 65.1^\circ \textrm{ N of E}$

b) $26.6 \textrm{ m, } 65.1^\circ \textrm{ S of W}$
