Problem 3 - A small airplane that has a mass of 1,500 lb,m is about to take off. The airplane hasa coefficient of lift of 1.0 at an Angle of Attack (AOA) of zero and it linearly increases by 0.1 every10 degrees; wings with a constant chord length of 3.5 ft and a total wingspan of 30 ft; a coefficientof drag of 0.3; and a frontal area of 40 ft? that linearly increases by 5 ft every 10 degrees. If theair is still, and the density of air is 0.076 lbm ft-3 at the ground levelwhat is the critical speed needed for takeoff?If the runway is 1000 ft long, the total coefficient of friction betweenthe road and the airplane is 0.25, what is the average thrust needed to achieve the critical takeoffspeed?
