16. The forces are all constant, so the total work done by them is given by WF x=netΔ,whereFnetis the magnitude of the net force and Δxis the magnitude of the displacement. We add the three vectors, finding the xand ycomponents of the net force: net 123net 23sin50.0cos35.03.00 N (4.00 N)sin35.0(10.0 N)cos35.02.13Ncos50.0sin35.0(4.00 N) cos50.0(10.0 N)sin35.03.17 N.xyFFFFF=− −°+°=−−°==−°=The magnitude of the net force is
