To calculate the work done by a person on the box, we need to multiply the force applied by the distance over which the force is applied.
In this case, the person applies a force of 400 newtons and pushes the box for a distance of 4 meters. Therefore, the work done by the person is:
Work = Force x Distance
Work = 400 N x 4 m
Work = 1600 joules
So, the correct answer is 1,600 joules.
To calculate the work done by the person, we use the formula:
Work = Force * Distance
Given:
Force = 400 Newtons
Distance = 4 meters + 1 meter (since the box slides forward an additional meter)
Calculating the work done:
Work = 400 Newtons * 5 meters
Work = 2000 Joules
Therefore, the correct answer is 2,000 joules.
To calculate the work done by a person, we can use the formula:
Work = Force × Distance
In this case, the person applies a force of 400 newtons and pushes the box for a distance of 4 meters. After he stops pushing, the box slides forward another meter.
So, the total distance the box moves is 4 meters + 1 meter = 5 meters.
Now we can calculate the work done:
Work = 400 newtons × 5 meters = 2,000 joules
Therefore, the work done by the person is 2,000 joules.
