Question description

The drawing shows a plane diving towards the ground and then climbing back upward. During each of these motions, the lift force L with arrow acts perpendicular to the displacement s with arrow, which has the same magnitude, 1.70  103m, in each case. The engines of the plane exert a thrust T with arrow, which points in the direction of the displacement and has the same magnitude during the dive and the climb. The weight W with arrow of the plane has a magnitude of 6.30  104N. In both motions, net work is performed due to the combined action of the forces L with arrowT with arrow and W with arrow.

Can someone please explain how to approach this problem to answer the following question?

(a) Is more net work done during the dive or the climb?
