An airplane is heading due south at a speed of 670 km/h.
A) If a wind begins blowing from the southwest at a speed of 110 km/h (average), calculate the velocity (magnitude of the plane relative to the ground.
B) Calculate the velocity (direction) of the plane relative to the ground.
C) Calculate how far from its intended position will it be after 17 minutes if the pilot takes no corrective action.
