A Boeing 777 landed at Chicago O’Hare Airport (668 m elevation) where the pressure is 98.8 kPa. Assume that the landing speed is 196.4 mi/hr. This 777 wing has a coefficient of drag of 0.034 and its wing area is 429.1 m2. What is the drag at the point where the aircraft just lands on the ground? Note that these conditions are non-standard so use altitude to calculate temperature then use the pressure given to calculate density.
