A truck moves 70m east, then moves 120m west, and finally moves east again a distance of 90 m. If east is chosen as the positive direction, what is the trucks resultant displacement?
1 answer
The truck ends up 160 miles east and 120 miles north of where it started. Perform a vector addition. It looks like you have a 3-4-5 right triangle, so the answer might be obvious.
