Consider a 700. g steel spike 12.0 cm long and a sledge hammer that exerts an average force of 6,000. N on the spike when it is being driven into the railroad track. The nail becomes warmer. Assuming all the mechanical energy of the sledge hammer stroke is converted into thermal energy, how many oC did the spike’s temperature increase? (Use the specific heat capacity of steel as 450. J/kg.oC.)
