Calculate the work done when a 18 N force pushes a cart 2.5 m.

To calculate the work done, you need to use the formula:

Work = Force × Distance

In this case, the given force is 18 N and the distance is 2.5 m.

So, the work done is:

Work = 18 N × 2.5 m

Work = 45 Joules

Therefore, the work done is 45 Joules.
