An automated winch system on a salvage vessel is used to pull a heavy container horizontally along the seabed.
The winch motor does 8.64×105 J8.64 \times 10^5\text{ J}8.64×105 J of useful work to drag the container a distance of 180 m180\text{ m}180 m.
Calculate the average horizontal force, in newtons, exerted by the winch on the container.
