Understanding the Concepts

* Work: Work is done when a force causes an object to move a certain distance. It's calculated by: Work (W) = Force (F) x Distance (d)

* Joules: Joules are the units of measurement for work and energy.

Solving the Problem

1. Rearrange the work equation: We need to find the force, so let's rearrange the equation to solve for F:

Force (F) = Work (W) / Distance (d)

2. Plug in the values:

Force (F) = 224 Joules / 32 meters

3. Calculate the force:

Force (F) = 7 Newtons (N)

Answer: A force of 7 Newtons must be used to do 224 Joules of work over a distance of 32 meters.
