The potential energy of a ball at the top of a hill is 15,000 J. Two-thirds of the way down the hill, the potential energy is 5476 J. What is the ball's kinetic energy at that point?

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object
