Q. An airplane is heading due south at a speed of 640 km/h. If a wind begins blowing from the southwest at a speed of 90 km/h (average), calculate the following.
(a) the velocity (magnitude and direction) of the plane relative to the ground
(b) how far from its intended position will it be after 10 min if the pilot takes no corrective action.
At what angle is the curve banked? The acceleration due to gravity is 9.8 m/s2.
