  This equation ‘could relate the takeoff distance 
  in terms of the takeoff velocity and acceleration 
  when the airplane is accelerated uniformly 
  from zero velocity to the final takeoff velocity. 
  Also, this expression could relate the landing 
  distance in terms of the landing velocity and 
  deceleration when the airplane is accelerated
