Question

Repeat the problem above, but reverse the order of the two legs of the walk; show that you get the same final result. That is, you first walk leg $\vec{B}$ , which is 20.0 m in a direction exactly
$40^\circ$ south of west, and then leg $\vec{A}$, which is 12.0 m in a direction exactly $20^\circ$ west of north. (This problem shows that $\vec{A} + \vec{B} = \vec{B} + \vec{A}$ .)
