Question

A construction worker drags a box across the floor. If the frictional force between the floor and the box is 12.2 newtons, how much work does friction do as the box moves 11.5 meters?

Answer 1

The work done is 140.3 J

Explanation:

• The work done is defined as the amount of force required or used to move an object over a particular distance. Hence, work done is the product of force in Newton and the distance in which the object moved in meters.
• Here, in the question, it is given that there is a frictional force acting on the box by the floor and the distance it moves. Hence, to get the answer to multiply frictional force and the distance. So, will get the work done as 140.3 J.
