How fast does water flow from a hole at the bottom of a very wide, 5.8-m-deep storage tank filled with water? ignore viscosity?

To calculate the speed of the water leaving we use the formula,

Here h is the height of the water above the hole and g is the acceleration due to gravity.

Given,

Substituting the given value in above formula we get

Thus, water flow from a hole at the speed is 10.7 m/s

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
