GO Figure 7-28 shows three forces applied to a trunk that moves leftward by 3.00 m over a friction- less floor. The force magnitudes are F = 5.00 N, F2 = 9.00 N, and F, 3.00 N, and the indicated angle is 0 = 60.0°. During the displacement, (a) what is the net work done on the trunk by the three forces and (b) does the kinetic energy of the trunk increase or decrease? *15 %3D %3D Fg Figure 7-28 Problem 15.
