PLEASE HELP ME Find the work done by a man who is pulling a box of 45kg of mass by means of rope which makes angle of 45 degrees.

Explanation:

No work is done by the man since we do not know the distance or displacement.

Work is only said to be done when the force applied on an object moves it through a particular distance.

 Work done  = Force x distance.

Since no distance is given in this problem, we can as well assume that the force applied is doing no work on the object.
