A person pushes the box he applies a force of 400 N and he pushes the box for distance of 4 m after he stops pushing the box slides forward another meter how much work was done by the person
To calculate the work done by the person in pushing the box, we need to use the formula:
Work = Force x Distance
Given that the force applied by the person is 400 N and the distance over which the force is applied is 4 m, we first calculate the work done by the person in pushing the box for the initial 4 meters:
Work = 400 N x 4 m
Work = 1600 Joules
After the person stops pushing the box, it slides forward another meter. The work done by the person to slide the box another meter can be calculated using the same formula:
Work = Force x Distance
Work = 400 N x 1 m
Work = 400 Joules
Therefore, the total work done by the person in pushing the box and causing it to slide forward another meter is:
Total Work = 1600 Joules + 400 Joules
Total Work = 2000 Joules
So, the person has done a total of 2000 Joules of work in pushing the box and causing it to slide forward another meter.
