A 2.00 kg-ball has zero kinetic and potential energy. Ernie drops the ball into a 10.0-m deep well. Just before the ball hits the bottom, the sum of its kinetic and potential energy is:

Question

Quizplus · Accepted Answer

The law of conservation of energy states that the total energy in a closed system remains constant. Initially, the ball has zero kinetic and potential energy. As it falls, potential energy is converted into kinetic energy, but the total energy remains zero.
