Chapter 07, Problem 015 GO The figure shows three forces applied to a trunk that moves leftward by 2.87 m over a frictionless floor. The force magnitudes are F1 = 4.69 N, F2 = 9.16 N, and F3 = 3.25 N, and the indicated angle is 8 = 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? (a) Number Units (b) () the tolerance is +/-5% Click if you would like to Show Work for this question: Open Show Work
