The drawing shows a plane diving toward the ground and then climbing back upward. During each of these motions, the lift force L acts perpendicular to the displacement s, which has the same magnitude, 1.28 x 103 m, in each case. The engines of the plane exert a thrust T, which points in the direction of the displacement and has the same magnitude during the dive and the climb. The weight W on the plane has a magnitude of 6.58 x 104 N. In both motions, net work is performed due to the combined action of the forces L, T, and W. Find the difference between the net work done during the dive and the climb.
