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 = 3.60 N, and F3 = 10.0 N, and the indicated angles are θ2 = 51.0 ˚ and θ3 = 34.0 ˚. What is the net work done on the canister by the three forces during the first 3.90 m of displacement?
