Question

If you jump off a 3 meter high diving board and do a cannonball into the pool, what happened?

Group of answer choices

The water will get colder.

The temperature of the water will increase by your mass times the specific heat of water

The thermal energy of the water will increase by an amount equal to the gravitational potential energy you had on the diving board.

The internal energy of the water will decrease by 3 times the specific heat of water.

Answer 1

Whenever we jump from a high diving board and do a cannonball into the pool , all the initial potential energy of the diver gets firstly converted into kinetic energy as it descends downwards towards the pool, and once it reaches the surface of water , all of its initial potential energy is converted into kinetic energy and then all this kinetic energy is converted into heat energy of the water. Thus , the thermal energy of the water will increase by an amount equal to the gravitational potential energy you had on the diving board. The basic principle lying underneath is due to the conservatory energy.
