An electric winch pulls a scientific instrument sledge across a flat ice sheet. The winch does 5.85 kJ of work in pulling the sledge a horizontal distance of 45 m in the direction of the force.
Calculate the average horizontal force, FFF, in newtons, that the winch exerts on the sledge.
Use the equation: work done=force×distance\text{work done} = \text{force} \times \text{distance}work done=force×distance
