Magnus has reached the finals of a strength competition. In the first round, he has to pull a city bus as far as he can. One end of a rope is attached to the bus and the other is tied around Magnus's waist. If a force gauge placed halfway down the rope reads out a constant 1450 Newtons while Magnus pulls the bus a distance of 2.05 meters, how much work does the tension force do on Magnus? The rope is perfectly horizontal during the pull.
