A person pushes a box. He applies force of 400 newtons, and he pushes the box for a distance of 4 meters. After he stops pushing, the box slides forward another meter. How much work was done by person?
The work done by the person is equal to the force applied multiplied by the distance moved in the direction of the force.
Work = Force × Distance
The force applied by the person is 400 newtons, and the distance moved in the direction of the force is 4 meters + 1 meter = 5 meters.
Therefore,
Work = 400 newtons × 5 meters = 2000 joules.
So, the person did 2000 joules of work.
To calculate the work done by the person, we can use the formula:
Work = Force × Distance
Given that the force applied by the person is 400 newtons and the distance moved by the box is 4 meters, we can substitute these values into the formula:
Work = 400 N × 4 m
Calculating this expression:
Work = 1600 N⋅m or 1600 Joules
Therefore, the person did 1600 Joules of work.
To calculate the work done by a person in pushing the box, we can use the formula:
Work = Force × Distance
In this case, the person applied a force of 400 newtons and pushed the box for a distance of 4 meters. So, we can substitute these values into the formula:
Work = 400 N × 4 m
By multiplying these values, we get:
Work = 1600 joules
Therefore, the person did 1600 joules of work in pushing the box.
