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 48 in waist. If a force gauge placed halfway down the rope reads out a constant 412.0 lbf while Magnus pulls the bus a distance of 55.0 in, how much work does the tension force do on Magnus? The rope is perfectly horizontal during the pull. Express the answer in both foot‑pound force (ft·lbf) and Newton‑meters (N·m).
