16. The forces are all constant, so the total work done by them is given by WF x = net Δ , where F net is the magnitude of the net force and Δ x is the magnitude of the displacement. We add the three vectors, finding the x and y components of the net force: net 1 2 3 net 2 3 sin50.0 cos35.0 3.00 N (4.00 N)sin35.0 (10.0 N)cos35.0 2.13N cos50.0 sin35.0 (4.00 N) cos50.0 (10.0 N)sin35.0 3.17 N. x y FF F F F =− − °+ °=− ° = =− ° = The magnitude of the net force is
