Problem: 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, while the other is tied around Magnus\'s 48 inch waist.
Part A: If a force gauge placed halfway down the rope reads out a constant 512.0 lbs while Magnus pulls the bus a distance of 28.0 inches, how much work does the tension force do on Magnus?
I need help to find how much work does the tension force do on Magnus and the rope is perfectly horizontal during the pull. Express your answer in both foot-pounds (ft-lb) and Newton-meters (N•m).
