## Homework Statement

An aircraft has a cruising speed of 100 m/s. On this particular day, a wind is blowing from the west at 75 m/s.

If the pilot wishes to have a resultant direction of due north, in what direction should the plane be pointed? What will be the plane displacement in 1.25 h?

## Homework Equations

## The Attempt at a Solution

I answered the other two parts of the question asking for the total displacement and velocity relative to the air or something. Where do I start with this?

I know it has to do with polar positives but my textbook has no examples.
