431 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 = 3.70 N, and F3 = 10.0 N, and the indicated angles are 82 = 49.0 and 03 = 31.0. What is the net work done on the canister by the three forces during the first 4.30 m of displacement? 82 Number i 18.67 Unit J
