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 part (a) of the drawing. The plane has a weight of magnitude 87500 N, and its engines provide a forward thrust . In addition, the lift force (directed perpendicular to the wings) and the force 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 60700 N. What are (a) the thrust and (b) the lift?
