You are on an airplane traveling 30° south of due west at 180 m/s with respect to the air. the air is moving with a speed 31 m/s with respect to the ground due north.
1) what is the speed of the plane with respect to the ground?
2) what is the heading of the plane with respect to the ground? (let 0° represent due north, 90° represents due east).
3) how far east will the plane travel in 1 hour?
