Suppose the Eskimo is pushing the same 50.0-kg sled across level terrain with a force of 51.5 N.

If he does 3.85 102 J of work on the sled while exerting the force horizontally, through what distance must he have pushed it?

Just for clarification, the question asks if he does 3.85 X 10^2 J of work.
