###### Problem

A disoriented physics professor drives 3.45 km north, then 2.45 km west, and then 1.50 km south.

Find the magnitude of the resultant displacement, using the method of components.

Find the direction of the resultant displacement measured west of north.

Select the correct vector-addition diagram (roughly to scale) of the resultant displacement.

Show that the resultant displacement found from your diagram is in qualitative agreement with the result you obtained by using the method of components.
