Energy Conservation With Conservative Forces: A lightweight object and a very heavy object are sliding with equal speeds along a level frictionless surface. They both slide up the same frictionless hill with no air resistance. Which object rises to a greater height?
A. The heavy object, because it has greater initial kinetic energy. B. The light object, because gravity slows it down less. C. The lightweight object, because the force of gravity on it is less. D. The heavy object, because it has more mass to carry it up the hill. E. They both slide to exactly the same height.
