Answer:

Step-by-step explanation:
Work is the product of force and distance.

The force is 500 Newtons and the couch is raised 12 meters above the ground.
Substitute these values into the formula.

Multiply.

- 1 Newton meter is equal to 1 Joule.
- So, our answer of 6000 N*m equals 6000 J

The work done to move a 500 Newton couch 12 meters is 6000 Joules. Therefore, choice D is correct.
