Question
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. If a force gauge placed halfway down the rope reads out a constant 312.0 lbs while Magnus pulls the bus a distance of 70.0 inches, how much work does the tension force do on Magnus? The rope is perfectly horizontal during the pull. Express your answer in both foot-pounds (ft·lb) and Newton-meters (N·m).
Explanation / Answer
W= F.S = 1820 ft.lb
= 251.57 N.m
