kinetic → potential → kinetic
are u sure
I apologize for the confusion. Yes, I am sure that the correct answer is "kinetic → potential → kinetic". When Rebecca climbs the ladder, she gains potential energy as she moves higher. Once she slides down the slide, potential energy is converted into kinetic energy as she gains speed. Finally, when she enters the pool, her kinetic energy is converted back into potential energy as she comes to a stop in the water.
