Question
On its takeoff roll, the airplane starts from rest and accelerates according to a = ao - kv² where ao is the constant acceleration resulting
from the engine thrust and -kv² is the acceleration due to aerodynamic drag. If að = 1.6 m/s², k = 0.000039 m ¹, and vis in meters per
second, determine the design length of runway required for the airplane to reach the takeoff speed of 271 km/h if the drag term is (a)
excluded and (b) included.
V0 = 0
Answers:
(a) Excluding drag, s= i
(a) Including drag, S= i
v=271 km/h
