Halliday, Resnick & Walker — Kinetic Energy and Work: Problem 14

Figure 7.12 shows an overhead view of three horizontal forces acting on a cargo canister that was initially stationary but now moves across a frictionless floor. The force magnitudes are \(F_1 = 3.00\text{ N}\), \(F_2 = 4.00\text{ N}\), and \(F_3 = 10.0\text{ N}\), and the indicated angles are \(\theta_2 = 50.0^\circ\) and \(\theta_3 = 35.0^\circ\). What is the net work done on the canister by the three forces during the first \(4.00\text{ m}\) of displacement?
