A $200-$lb cable is $80$ ft long and hangs vertically from the top of a tall building. How much work is required to lift the cable to the top of the building?

The density $($or unit weight$)$ is $2\mathrm{.}5l\frac{b}{f}t.$

Let represent the vertical distance from $($and above$)$ the initial position of the low end of the cable.

If we integrate force over distance, we have

${\displaystyle \underset{0}{\overset{80}{}}}(80-x)[2\mathrm{.}5dx]$

True

False
