If the height of the slope is, how much work is done by friction over the distance? Chapter references are from the CPO IPC book. Based on conservation of energy, we can find the height that the ball travels with this remaining kinetic energy. The relationship between both scales is consistent for all temperatures, as shown by the straight line. Thus, not all mixtures are solutions. Conservation of energy shows that the initial energies will be equal to the final energies.
