The figure shows three forces applied to a trunk that moves leftward by 3.44 m over a frictionless floor. The force magnitudes are
F1 = 4.94 N, F2 -8.81 N, and F3 - 2.72 N, and the indicated angle is 8 - 60° (a) During the displacement, what is the network done on
the trunk by the three applied forces, the gravitational force, and the normal force? (b) Is there a net transfer of energy to or from
the trunk? (c) Does the kinetic energy of the trunk increase or decrease?
