How do I start this question? The figure shows three forces applied to a trunk that moves leftward by 3.01 m over a frictionless floor. The force magnitudes are F1 = 5.50 N, F2 = 8.72 N, and F3 = 3.11 N, and the indicated angle is θ = 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?
You start by posting the diagram please! :-)
Thank you! @MrNood

calculate the net force in the horizontal direction. as that is the direction in which movement occurs, you can apply the fundamental/seminal definition: \(Work = Force \times Distance\). specifically, the work done by force is that fore times the distance travelled in the direction of that force..... |dw:1445544756969:dw|
