Carleigh Molina · Answer 1

The correct answer for this question would be A) Increases because the potential energy of the boulder was it resting on the top of the cliff, and the kinetic energy was the boulder accelerating to the ground so it was increasing and in motion.

Carter Leon · Answer 2

Because of releasing with 0 kinetics energy, the kinetic energy stays the same
