ake Earth to be the object of reference. Two people start and end their trips at different locations but have the same displacement vectors in the reference frame. The motion of the two people is one dimensional, the positive direction is to the right. Suppose the initial and final positions of the first person are xinitial=−20mxinitial=−20m and xfinal=30mxfinal=30m. Find the final position of the second person if his initial position is xinitial=20mxinitial=20m.
