## Homework Statement

A small plane flies a heading of 200km/h [W]. The wind speed is 50.0km/h [N]

a) Determine the resultant groundspeed and direction of the plane

b) What heading would the plane need to take to travel due west, and what would his ground speed be?

## Homework Equations

r^2=a^2 + b^2

## The Attempt at a Solution

So for a):

r^2 = (200)^2 + (50.0)^2

r = 206 km/h

tan(theta) = 50/200

(theta) = 14

Therefore, the resultant groundspeed and direction is 206 km/h W14N.

But, for b), I'm not so sure what the difference is between what I just did for a) compared to the question b). I'm sorry am I missing anything?
