If you walk10 meters north and then 6 meters south, you won’t end upwhere you started.Q3.2No, the magnitude of the displacement is always less than orequal to the distance traveled. If two displacements in the samedirection are added, then the magnitude of their sum will beequal to the distance traveled. Two vectors in any otherorientation will give a displacement less than the distancetraveled. If you first walk 3 meters east, and then 4 meterssouth, you will have walked a total distance of 7 meters, butyou will only be 5 meters from your starting point.Q3.3The largest possible magnitude of RAB=+is 7 units, found when Aand Bpoint in the same
