Amount of work on person by vertical component?

A person weighing 200N sits on a sled and is pulled 75m horizontally at a constant speed by a force of 100N acting on the sled at an angle of 30 degress to the horizontal. What is the amount of work on the person by the vertical component of the 100 N force? Why is this true?
