Question

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 F1 = 3.50 N, F2 = 4.50 N, and F3 = 20.0 N, and the indicated angles are ?2 = 50.0

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 F1 = 3.50 N, F2 = 4.50 N, and F3 = 20.0 N, and the indicated angles are ?2 = 50.0A degree and ?3 = 39.0 A degree. What is the net work done on the canister by the three forces during the first 4.00 m of displacement?

Explanation / Answer

Fnet x = F3*cos39 - F1 - F2*sin50

Fnet x = 9.595 N

W = Fnetx*x = 34.38 J
