The Cessna Cardinal, a single-engine light plane, has a wing with an area of 16.2 m^2, and an aspect ratio of 7.31. Assume the span efficiency factor is 0.62. a. If the airplane is flying at standard sea-level conditions with velocity of 251 km/h, what is the induced drag when the total weight is 9800N b. Calculate the induced drag when the
