A jet plane is flying with a constant speed along a straight line, at an angle of 35.0 ° above the horizontal. The plane has a weight W ? of magnitude 88,500N , 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 .
1. Draw a free body diagram of the plane.
2. What is the magnitude of the thrust force?
3. What is the magnitude of the lift?
