A person applies 110J to lift a box 5 meters off the ground. How much force was required by the person?

1 answer

To find the force required to lift the box, we can use the work-energy principle, which states that work done (W) is equal to the force (F) applied times the distance (d) over which the force is applied:

\[ W = F \times d \]

In this scenario, we have:

  • Work done \(W = 110 , \text{J}\)
  • Distance \(d = 5 , \text{m}\)

We can rearrange the formula to solve for force \(F\):

\[ F = \frac{W}{d} \]

Now, substituting the known values into the equation:

\[ F = \frac{110 , \text{J}}{5 , \text{m}} = 22 , \text{N} \]

The force required by the person to lift the box is 22 Newtons.
