How much work is done if an object moves 4.5 m in has 12 newtons of force acting on it

Given Data:

Displacement of objects (s) = 4.5m,

Force applied (F) = 12 N,

Work done (W)=?

Work is defined as an effort done in order to achieve the result. In this case an effort done to move the object to certain distance.

Mathematically,  From Joules law, W =  Force  × displacement

                                                         W = 12×4.5

                                                             = 54 J
