2/49 on its takeoff roll, the airplane starts from rest and accelerates according to a=a0−kv2, where a0 is the constant acceleration resulting from the engine thrust and −kv2 is the acceleration due to aerodynamic drag. if a0=2 m/s2, 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.
