To calculate the speed of the water leaving we use the formula,
[tex]v=\sqrt{2gh}[/tex]
Here h is the height of the water above the hole and g is the acceleration due to gravity.
Given, [tex]h=5.8 m[/tex]
Substituting the given value in above formula we get
[tex]v=\sqrt{2\times9.8 m/s^{2}\times5.8m }[/tex]
[tex]v=\sqrt{113.68}[/tex]
[tex]v=10.7m/s[/tex]
Thus, water flow from a hole at the speed is 10.7 m/s
