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 2750 2750 Newtons while Magnus pulls the bus a distance of 1.60 1.60 meters, how much work does the tension force do on Magnus? The rope is perfectly horizontal during the pull.

The workdone is

The free body diagram is shown on the first uploaded image

From the question we are given that

            The force is on the force gauge  

             The distance that Magnus pulled the bus  

Generally  the workdone by the tension force on Magnus is

This negative sign show that is tension force  is in the opposite direction to Magnus movement (i.e the movement of the bus )

Substituting value we have

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
