Suppose you first walk 9.5 m in a direction 20.0° west of north and then 19.5 m in a direction 40.0° south of west. (a) How far are you from your starting point in meters? (b) What is the angle, in degrees, of the compass direction of a line connecting your starting point to your final position measured south of west? (c) Repeat part (a), but for the second leg you walk 19.5 m in a direction 40.0° north of east. (d) Repeat part (a), but now you first walk 9.5 m in a direction 40.0° south of west and then 19.5 m in a direction 20.0° east of south.
