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 = 3.50 N, and F3 = 10.0 N, and the indicated angles are θ2 = 52.0 ˚ and θ3 = 30.0 ˚. What is the net work done on the canister by the three forces during the first 4.20 m of displacement?

We find work by the following formula:
"A=(F_1+F_2\\cdot cos\\theta_2+F_3\\cdot cos \\theta_3 )\\cdot L"
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
