A Jet plane is flying with a constant speed along a straight line, at an angle of 30.0 above the horizontal, as shown in (a) of the drawing. The plane has a weight W of magnitude 87600 N, and its engines provide a forward thrust T. In addition, the lift force I (directed perpendicular to the wings) and the force R of air resistance (directed opposite to the motion) act on the plane. Part (b) of the drawing shows the free-body diagram of the plane. The air resistance has magnitude 62600 N. What are (a) the thrust and (b) the lift?
