# If a 200 pound cable is 100 feet 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?

Since the density of the cable is

The work required to lift the cable to the top of the building is calculated using the formula for work done against gravity:

Work = Force × Distance

In this scenario:

- The force exerted by the cable is its weight, which is 200 pounds.
- The distance the cable needs to be lifted is the height of the building, which is not provided in the question.

To calculate the work required, you need to know the height of the building. Once you have the height, you can multiply the force (200 pounds) by the distance (height of the building in feet) to find the work required.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
