Kinetic energy

Figure 7 -28 shows three forces applied to a trunk that moves leftward by 3.00 m over a frictionless floor. The force magnitudes ate F1 = 5.00 N, F2 = 9.00 N, and F3 =3.00 N, and the indicated angle is θ = 60.0°. During the displacement, (a) what is the net work done on the trunk by the three forces an) does the kinetic energy of the trunk increase or decrease?
