Question

A person starts driving and travels 3 km east to a store. the person then turns around and travels 1 km west to another store. finally, the person travels 2 km west, back to the starting point.

what is the magnitude of the displacement this person traveled?

Answer 1

D(displacement) = 3 km E + 1 km W + 2 km W = 0

Total displacement (vector) = 0

Total displacement (scalar) = 6 km

magnitude implies a total displacement of 6 km
