A crane hoist like the one shown in ▶ Figure 5.25 lifts a load of 1.0 metric ton a vertical distance of 25 m in 9.0 s at a constant velocity. How much useful work is done on the load by the hoist each second?
THINKING IT THROUGH. By definition, the useful work done each second (i.e., per second) is the power output, so this is what needs to be found.
