Answer:
6000J.
Explanation:
Potential Energy is the energy type that is determined according to the position of the object and is stored as the energy that has the potential to be converted into kinetic energy and to do work.
Kinetic Energy is the energy type that objects are considered to have according to their motion and velocity.
Bernie has 7000J potential energy and when he dives into the swimming pool he has 1000J of kinetic energy. Since energy is always converted either from kinetic to potential or potential to kinetic energy and the sum of the is always the same, he converted 6000J of his potential energy into kinetic energy and has 1000J of potential energy stored. Therefore his kinetic energy must be 6000J when his potential energy reduces to 1000J.
I hope this answer helps.
