1. The problem statement, all variables and given/known data 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? 2. Relevant equations r^2=a^2 + b^2 3. 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?
