In 1 minute, a mass of 9 000 kg of water flows through the turbines. The speed of the water is 30 m/s
Calculate the total kinetic energy of the water passing through the turbines in 1 minute.
Give your answer in kilojoules (kJ).

400 ounces.

Explanation:

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.

i think its d if wrong im sorry
