A plane flies due north at 225 km/h. A wind carries it due east at 55 km/h. What are the magnitude and direction of the plane's resultant velocity?

drwls,
Add the two vectors. Since they are perpendicular, you can get the magnitude from the Pythagorean theorem.
The ratio 55/225 is the tangent of the resultant ground velocity, angle east of north

Kiley,
How do you add the vectors?
