D) It is turned into heat by sliding friction.

Question

Quizplus · Accepted Answer

The kinetic energy of the child riding a bike and skidding to a stop is turned into heat by sliding friction. As the bike skids, the friction between the bike's tires and the ground generates heat, dissipating the bike's kinetic energy.
