## Homework Statement

An airplane flies with a velocity of 55.0 m/s [ 35o N of W] with respect to the air (this is known as air speed). If the velocity of the airplane according to an observer on the ground is 40.0 m/s [53o N of W], what was the wind velocity?

## Homework Equations

Pythagorean theorem, breaking into components, sine and cosine law

## The Attempt at a Solution

I tried adding the negative of the airplane vector to the ground vector and using the pythagorean theorem to find the other side but apparently that is wrong. THE TEACHER POSTED A VIDEO TRYING TO EXPLAIN IT I STILL DIDNT UNDERSTAND IT. HERE IS THE VIDEO : http://www.educreations.com/lesson/view/module-1-2-question-2/16555555/
