On its takeoff roll, the airplane starts from rest and accelerates according to a=a0-k v^2, where a0 is the constant acceleration resulting from the engine thrust and -k v^2 is the acceleration due to aerodynamic drag. If a0=2 m / s^2, k=0.00004 m^-1 and v is in meters per second, determine the design length of runway required for the airplane to reach the takeoff speed of 250 km / h if the drag term is (a) excluded and (b) included | Numerade

SOLVED: To take off from the ground an airplane must reach a sufficiently high speed The velocity required for the takeoff the takeoff velocity, depends on several factors including the weight of the aircraft and the wind velocity:
