The correct answer is 2,000 joules.
Work done = Force x Distance
Work done = 400 newtons x 4 meters
Work done = 1,600 joules
Since the box slides forward another meter after the person stops pushing, the total work done would be:
Work done = Force x Distance
Work done = 400 newtons x 5 meters
Work done = 2,000 joules
Therefore, the correct answer is 2,000 joules.
