AP Physics C: Mechanics
3.2 Work
A crate moves across a horizontal floor through a straight displacement of magnitude d directed along the positive x-axis. Four constant forces act on the crate during this displacement, as specified in the table.
Which of the following correctly ranks the work W done on the crate by each force during the displacement, from greatest to least?
| Force | Magnitude | Angle relative to +x-axis |
|---|---|---|
| Force 1 | 2F_0 | 0 degrees |
| Force 2 | 3F_0 | 60 degrees |
| Force 3 | 4F_0 | 90 degrees |
| Force 4 | F_0 | 180 degrees |
