Eric Baldwin · Answer 1

The total displacement of the car is 2 meters south

Explanation:

As the car went south 10m, and then went back over it initial path for 8 meters, the actual distance registered in the car's odometer will be 18 m, but as far as vector displacement in its final position, this will be 2 meters south (10m - 8m=2m).

Notice that the displacement vector is defined as the final position minus the initial position, which gives a distance of 2 from the origin, in the suoth direction. meters
