The figure below 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 2.90 N, F= 3.90 N, and F3 = 20.0 N, and the indicated angles are 02 = 50.0 and 03 = 34.0. What is the net work done on the canister by the three forces during the first 4.00 m of displacement? J Additional Materials LeBook 8
