Haile's plane travels forward for a few feet and then begins to fall. What would explain the plane's ability to travel forward for a few feet without falling? A The speed of the plane is equal to the speed of the oncoming air that pushes on the plane. B The speed of the plane is greater than the speed of the oncoming air that pushes on the plane. C The force of the air pushing up on the plane is equal to the force of gravity pulling down on the plane. D The force of gravity pulling down on the plane is greater than the force of the air pushing up on the plane.
