<h3>
Answer:</h3>
500 Joules
<h3>
Explanation:</h3>
<u>We are given;</u>
- Force is 100 N
- Distance is 5 m
We are required to calculate the work done;
- Work done is the product of force and distance.
- That is, work done = Force × distance
- Work is measured in Joules
Thus, in this case;
Work done = 100 N × 5 m
= 500 Joules
Thus, the work done in moving the box is 500 joules
