If a glass knocked off a table horizontally with a velocity of 7 ft/s and lands 2.5 feet from the table. What was the height of the table that it fell off?

Explanation:

The U.S. Environmental Protection Agency (EPA) defines point source pollution as “any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack” (Hill, 1997). Factories and sewage treatment plants are two common types of point sources.
