Homework Statement

3. A person going for a walk follows the path shown in Figure P3.57 (y1 = 320 m, http://xs124.xs.to/xs124/08064/theta_1_452.gif =[/URL] 58.0°). The total trip consists of four straight-line paths. At the end of the walk, what is the person's resultant displacement measured from the starting point?
