Water is poured into a cylindrical container (radius R=5.00{“version”:”1.1″,”math”:”R=5.00″} cm) to a height h=20.0{“version”:”1.1″,”math”:”h=20.0″} cm. The container rests on the edge of a table a height H=1.00{“version”:”1.1″,”math”:”H=1.00″} m above the ground. If a small hole of radius r=1.50{“version”:”1.1″,”math”:”r=1.50″} mm is made in the container at h/4{“version”:”1.1″,”math”:”h/4″} from the bottom, how far does the water travel from the edge of the table before hitting the ground?
