SUMMARY
The discussion centers on calculating the change in temperature of a 5-gram copper coin dropped from a 300-meter building, reaching a terminal velocity of 45 m/s. The conservation of energy principle is applied, where the initial potential energy is equated to the sum of the heat energy (delta Q) and kinetic energy (KE). The final calculation yields a temperature change of approximately 4.98 °C, confirming that the units for temperature are correctly derived as °C after canceling out kg and J.
