The best answer that describes the energy changes during Rebecca's time on the slide is:

potential → mechanical → kinetic

Here's the breakdown of the energy changes:

  1. Potential Energy: As Rebecca climbs the ladder, she gains gravitational potential energy due to her height above the ground.
  2. Mechanical Energy: At the top of the slide, she holds both potential energy and some amount of mechanical energy as she prepares to slide down.
  3. Kinetic Energy: As she slides down the slide, her potential energy is converted into kinetic energy, which increases as she accelerates towards the pool.

So, the correct answer is potential → mechanical → kinetic.
