Atrunk is dragged 3.0 meters across an attic floor by a force of 2.0 n. how much positive work is done on the trunk?

The work done is the product of the force exerted and the displacement of the object in the same direction as the force. Mathematically,
                                    Work = Force x displacement
Substituting the known values,
                                   Work = (2.0 N) x (3.0 m) = 6 Nm
Thus, the positive work done is 6 Nm.
