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