A plane is toward the south at a speed of 475 km / h. The wind begins to blow from the southwest at a speed of 100 km / h (average). (Hint: First draw a diagram.) A) What is the velocity (magnitude and direction) of the ground plane, (b) To what extent the course will be after 11 minutes if the pilot does not take corrective measures?
Surely it would depend on the side where the drag coefficient of the aircraft?
