A student lifts a box of books that weighs 200 n. The box is lifted 4.0 m. How much work does the student do on the box?

800 J is the work done by the student to lift the box of books.

Explanation:

Work done is the measure of force required to move an object from one position to another. So it can be determined by the product of force and displacement of the object.

Work done to lift the box of books = Force acting on the box × Distance the box is lifted.

So here the displacement or the distance of the box being lifted is given as 4 m and the force acting on the box is given as 200 N.

Then, work done = 200 × 4 = 800 J.

So 800 J is the work done by the student to lift the box of books.

this would be about 43%
