9. Rebecca climbs the ladder of a large water slide, waits her turn at the top, and then slides down the slide into a pool. Which answer best describes the energy changes during her time on the slide?(1 point)Responsespotential → mechanical → kineticpotential → mechanical → kinetickinetic → potential → kinetickinetic → potential → kineticpotential → kinetic → potentialpotential → kinetic → potentialkinetic → mechanical → potential

1 answer

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

potential → mechanical → kinetic.

Here's the reasoning:

  1. Potential Energy: When Rebecca is at the top of the ladder, she has gravitational potential energy due to her height.
  2. Mechanical Energy: As she prepares to slide down, her body exerts a mechanical force against the slide.
  3. Kinetic Energy: As she slides down, her potential energy is converted into kinetic energy as she speeds up.

Thus, the transition from potential energy at the top, through mechanical energy during the slide, to kinetic energy at the bottom best represents the energy changes involved in her descent.
