Ahorizontal force of 20 newtons eastward causes a 10-kilogram box to have a displacement of 5 meters eastward. the total work done on the box by the 20-newton force is (1)40 j (2)100 j (3)200 j (4)1000 j

Explanation:

The Work done by a Force refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.  

It should be noted that it is a scalar magnitude, and its unit in the International System of Units is the Joule (like energy). Therefore, 1 Joule is the work done by a force of 1 Newton when moving an object, in the direction of the force, along 1 meter:  

Now, when the applied force is constant and the direction of the force and the direction of the movement are parallel, the equation to calculate it is:  

(1)  

Where is the distance traveled by the object.

In this case:

 and

Hence:
