Homework Help: Physics warming a nail

Posted by Mary on Sunday, September 20, 2009 at 9:57am.

2.) Pounding a nail into wood makes the nail warmer. Consider a 5-g 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 13.3oC. (Assume the specific heat capacity of steel is 450 J/kg*oC.)

I used the formula Q = cm(change in temp)
to get (Q being quantity of heat):
Q = 450J/kg(5g)13.3oC
I'm not sure where the 500N or 6cm come in.
