Explanation:
The bullet is stopped by the ice block, which cools down the first one. The energy is dissipated in the form of heat, which melts part of the ice block. This phenomenon is modelled after the First Law of Thermodynamic, which is a generalization of the Principle of Energy Conservation:
The mass of ice that is melt is:
