Kinetic energy is the energy of the motion.

This is because the kinetic energy can be calculated by using the formula,

K.E.=1/2 mv^2

where, v is the velocity of moving body i.e. the body is in motion.

Speed can be found through the application of concepts related to potential energy and kinetic energy, for which you have

$KE = PE$

$\frac{1}{2}mv^2 = mgh$

Where,

m = mass

v = Velocity

g = Gravitational acceleration

h = Height

Re-arrange to find the velocity we have,

$v^2 = 2gh$

$v = \sqrt{2gh}$

$v = \sqrt{2(9.8)(0.54)}$

$v = 3.253m/s$

Therefore the speed at which water squirts out of the hole is .3253m/s
