Question
A jet plane is flying with a constant speed along a straight line, at an angle of 25.5° above the horizontal, as Figure 4.30a indicates. The plane has weight vector W whose magnitude is 86500 N, and its engines provide a forward thrust vector T of 103000 N. In addition, the lift force vector L (directed perpendicular to the wings) is 78100 N and the air resistance vector R is 65800 N. Suppose that the pilot suddenly jettisons 3150 N of fuel. If the plane is to continue moving with the same velocity under the influence of the same air resistance vector R , by how much does the pilot have to reduce each of the following?
