Quizplus · Accepted Answer

The block of ice will start with all potential energy at the top of the incline, which will be converted to kinetic energy as it slides down. At the bottom of the incline, all potential energy will have been converted to kinetic energy, so the kinetic energy will be at its maximum. Therefore, the block of ice must have half its maximum kinetic energy halfway down the incline, as it has converted half of its potential energy to kinetic energy at this point.
