The figure here shows an overhead view of three horizontal forces acting on a cargo canister that was initially stationary but that now moves across a frictionless floor. The force magnitudes are F1 = 2.80 N. F2 = 3.90 N and F3 = 10.0 N, and the indicated angles are θ2 = 48.0∘ and θ3 = 34.0∘. What is the net work done on the canister by the three forces during the first 4.30 m of displacement? Number Unit
