4.) From an origin, a person walks 15m, 40°North of West. After which he walks another 20m North. What is the length of the shortest path between the origin and the final (current) location of the person? We assume that North and East are along the positive y- and x- axes, respectively. ++ N y E

What is the length of the shortest path between the origin and the final (current) location of the person? We assume that North and East are along the positive y- and x- axes, respectively. Hint: You have to demonstrate that this is a vector addition problem. Also, for a vector C, its length, |C = /C + C3 , where Cx and Cy are the x- and y- components of C.
