# Determining wind velocity vector.

• Jonathan Teas

## Homework Statement

A light plane is headed due south with a speed of 185km/h "relative to still air". After 1.0hr, the pilot notices that they have only covered 136km. And that their direction is Southeast 45 degrees. What is the wind velocity?

## Homework Equations

Im guessing you have to use i, j substitution, but I am just not sure of how or what you would do.

## The Attempt at a Solution

I drew it out, and tried solving it trigonometricly...Failed. Tried to look at it the same way as problems with someone swimming and a current pushing them away from their destination point, but I just couldn't figure it out.

$\vec{A}$=$\vec{B}$ + $\vec{C}$

Vector B and C not necessarily orthogonal as in river crossing.
