Suppose you first walk 12.0 m in a direction 20° west of north and then 20.0 m in a direction 40.0° south of west
Suppose you first walk 12.0 m in a direction 20° west of north and then 20.0 m in a direction 40.0° south of west. How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (If you represent the two legs of the walk vector displacements A and B, as in Figure 3.56, then this problem finds their sum R = A + B.)
