An object that falls from the roof of a building starts with potential energy that becomes kinetic energy as the object falls. When the object strikes the ground, some of the kinetic energy is dissipated into the atomic-level motion of the particles that make up the object, and its temperature increases. If a 2.00 kg piece of iron fell from the roof of a building that was 25.5 m tall, what is the maximum temperature change (in C) that it could experience? (In practice, the temperature change would be much less than this because a significant amount of energy would be dissipated into the ground.) Assume that g = 9.8 m/s2 and Ciron = 460 J/(kg C)
