Calculating Airplane Velocity with Wind: A Study

[soccer5]

Homework Statement

An airplane is flying at [80.0, 50.0(degrees)] m/s when there is no wind. Then the wind begind to blow at [18.0, -20 (degrees)] m/s.

a) if the pilot does not change the heading of the plane what will be the resultant velocity over the ground?

b) In order to maintain the same heading and speed as before, how should the pilot now direct the plane??

The Attempt at a Solution

I know how to do part a.
But i have no clue about part b
please help??

Any ideas/attempts?

no idea.
we never did anything like that in class.

Well, you only have to regard the "same speed and heading as before" as the resultant velocity of the plane in case b).
