Acar travels 12 kilometers due north and then 7. 8 kilometers due west going from town a to
town b. what is the magnitude of the displacement

14.3 km

Explanation:

We motion of the car consists is split in two parts:

- A first motion 12 km north

- A second motion 7.8 km west

The two motions are in directions perpendicular to each other: this means that we can find the magnitude of the net displacement by using Pythagorean's theorem, therefore:

where

Substituting, we find
