An AV-8B Harrier flies in level forward flight at a constant velocity. The exhaust vents are deflected down at an angle of 80°. The drag force on the plane is F = KV2, where K = 8 kg/m. Neglect the thrust force associated with the air intake. If the weight of the plane is 60,000 N and the plane is moving slowly enough that the lift force of the air flowing over the wings can be neglected, find the steady forward velocity of the plane. Also find the necessary engine thrust force.
