The figure here shows an overhead view of three horizontal, Ask an Expert

Academics

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 = 2.90 N, F2 = 3.70 N, and F3 = 10.0 N, and the indicated angles are θ₂ = 51.0^oand θ₃ = 31.0^o. What is the net work done on the canister by the three forces during the first 4.50 m of displacement?
