Question

* A body of mass "m" is placed on a rough horizontal surface of coefficient o
friction "u". A force "F" acts on the body parallel to the surface such that is moves
with an acceleration "a" through a displacement "S"
The work done by the frictional force is
W = f S = (F-ma)S W = u mgs
[:f = umg]​
