The Cessna Cardinal, a single-engine light plane, has a wing with an area of 16.2 m^2 and Aspect Ratio of 7.31. Assume that the Oswald efficiency factor is 0.62. If the plane is flying at a standard sea-level condition with a velocity of 251 km/h, what is the induced drag when the total weight is 9800N ?
