The mass of an empty F-16 is roughly 8,708 kg. What must the net force on the plane be to accelerate the plane at a rate of 4 g's (4 Earth gravities, 1 g = 9.81 m/s^2 )? If the drag on the plane is -100,000. N, what must by the F-16's thrust? (Answers: F-B Diagram; 4 g's = 39.24 m/s^2 F = 341,702 N; T = 441,700 N; 2 pts)
