A horizontal force of 25 newtons pushes a box a distance of 30 meters across the floor. How much work is done by the force?

W = f*d = 25 * 30 = 750

To determine the amount of work done by a force, you need to multiply the magnitude of the force by the distance over which it acts. In this case, the magnitude of the force is 25 newtons and the distance is 30 meters.

So, the work done by the force can be calculated using the formula:

Work = Force x Distance

Substituting the values, we have:

Work = 25 newtons x 30 meters

Multiplying these values together gives us:

Work = 750 newton-meters, or Joules (J)

Therefore, the work done by the force is 750 Joules.
