It takes 50.0 j to push a large box 4.00 m across a floor. assuming the push is in the same direction as the move, what is the magnitude of the force on the box?

12.5 Newtons

Work done is defined as the product of force and distance covered or moved. It is measured in joules.

Work done = Force × distance

Therefore; making force the subject;

Force = work done/distance

         = 50.0 J/ 4.00 m

         = 12.5 Newtons.
