this problem. 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, 4.21
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 5.88 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.

Consult Interactive LearningWare 12.1 for help in solving this problem. During an all-night cram session, a student heats up a 0.417 liter (0.417 x 103 m3) glass (Pyrex) beaker of cold coffee. Initially, the temperature is 20.0 °c, and the beaker is filled to the brim. A short time later when the student returns, the temperature has risen to 96.5 °C. The coefficient of volume expansion of coffee is the same as that of water. How much coffee (in cubic...
