The principle of conservation of energystates that energy is neither created nor destroyed. Which of thefollowing describes the transformation of energy in thisproblem?

Conservation of energy does not apply toproblems involving nonconservative forces. Thus, the potentialenergy slowly disappears during Albertine's trip.
The potential energy was turned intoAlbertine's kinetic energy, which was then converted into internal(thermal) energy.
The potential energy was turned intoAlbertine's kinetic energy, which is now stored in the floor asfrictional potential energy.
The potential energy was turned into elasticfrictional energy, creating the frictional force.
