Answer:
<h2>The work done is 0.882 Joules.</h2>Explanation:
To calculate the work, we need to find all forces that are involved in the movement.
As you can analyse, the body is the force that make the box to move, and the friction force is opposite to it, we cannot forget about the friction. So, we have to calculate the resultant force to this context.
So, to find we use:
; where
The friction force would be:
Then, the resultant force is:
Now, we calculate the work:
Therefore, the work done is 0.882 Joules.
