The figure shows three forces applied to a trunk that moves leftward by 3.15 m over a frictionless floor. The force magnitudes are F₁ = 5.49 N, F₂ = 9.44 N, and F3 = 3.02 N, and the indicated angle is = 60°. (a) During the displacement, what is the net work 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?
