I Pounding a nail into wood makes the nail warmer. Consider a 5-gram steel nail 6 cm long and a hammer that exerts an average force of 500 N on the nail when it is being driven into a piece of wood. The nail becomes hotter. Show that the increase in the nail’s temperature is 13.3°C. (Assume that the specific heat capacity of steel is 450 J/kg°C.)
