Question

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?

Answer 1

Answer;

12.5 Newtons

Explanation;

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.
