Textbook Question

Chapter 7, Problem 15P

GO Figure 7-28 shows three forces applied to a trunk that moves leftward by 3.00 m over a friction- less floor. The force magnitudes are 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 and (b) does the kinetic energy of the trunk increase or decrease?
