You get a job delivering water. You calculate how much work is done picking up each 20 L bottle of water and raising it vertically 1 m. For every 100 bottles you deliver, you will use Select (g =
9.8 m/s2)
-196J
-2,000 J
-19,600 J
-196,000J

The work done by picking up 100 20-L bottles and raising it vertically 1 meter is 19614 joules.

Explanation:

By the Work-Energy Theorem, the work needed to raise vertically 100 bottles of water is equal to the gravitational potential energy, units for work and energy are in joules:

(1)

Where:

- Work.

- Gravitational potential energy.

The work is equal to the following formula:

(2)

Where:

- Number of bottles, dimensionless.

- Density of water, measured in kilograms per cubic meter.

- Volume, measured in cubic meters.

- Gravitational acceleration, measured in meters per square second.

- Vertical displacement, measured in meters.

If we know that , , , and , then the work done is:

The work done by picking up 100 20-L bottles and raising it vertically 1 meter is 19614 joules.
