Calculate the Force Applied by Mailman

What is the force used by a mailman who performed 588 J of work by lifting a box 1.4 m? The force the mailman applied to lift the box can be calculated using the formula Force = Work/Distance. Substituting the given values, 588 J (work) divided by 1.4 m (distance), you find that the mailman applied a force of 420 N.

In a physics problem, when a mailman performs 588 J of work by lifting a box 1.4 m, the question arises: How much force did the mailman apply to lift the box?

To solve this problem, we can use the formula for calculating force, which is Force = Work/Distance. The work done by the mailman is given as 588 J and the distance over which the work was done is 1.4 m.

Substituting these values into the formula, we get:

Force = 588 J / 1.4 m

Calculating this expression, we find that the force applied by the mailman is 420 N. Therefore, the correct answer is option a. 420 N.

This means that the mailman exerted a force of 420 Newtons to lift the box over a distance of 1.4 meters. The force applied is directly proportional to the work done and the distance covered, as per the formula.
