A jet plane is flying with a constant speed along a straight line, at an angle of 30.0? above the horizontal. The plane has a weight W? of magnitude 86,500N, and its engines provide a forward thrust T? . In addition, the lift force L? (directed perpendicular to the wings) and the force R? of air resistance (directed opposite to the motion) act on the plane and has magnitude 59,700N.
Draw a free body diagram of the plane.
What is the magnitude of the thrust force?
What is the magnitude of the lift?
