You need to break the velocity vector into its components. The northerly component is the y-component and the westerly component is the x-component.
The components are v cos(theta) and v sin (theta) where v is a the velocity and theta is the angle from North.
If I do any more, I will have done the question for you.

You can find out more by visiting the splung.com page on vectors. http://www.splung.com/content/sid/1/page/vectors
