1. The problem statement, all variables and given/known data 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. Which rises to a greater height? A) The heavy object, because it has greater kinetic energy. B) The light object, because it has smaller kinetic energy. C) The lightweight object, because it weighs less. D) The heavy object, because it weighs more. E) They both slide to the same height. 2. Relevant equations W=-mg 3. The attempt at a solution I was thinking that the answer is (C) , since the object is light and gravity pulls less on it than the heavy object and it can travel further distance. Any ideas?
