Force applied: calculating increase in temperature (work mostly done, need help!)

spidey64

Ok, I need to calculate the increase in temperature of a nail hit by a hammer with force of 500N. The length of the nail is .06m, so the work done and, I'm assuming, the energy added to the nail (Q) is 30 Joules. The specific heat capacity of the nail is 450 J/kg *C(degrees Celsius). By using the formula for finding the specific heat capacity : Q/(change in Temp x mass), I then found that the (change in Temp x m) = .0667 kg*C, but how the heck do I find the mass of the nail to single out the temp value?

really? no ideas at all? or am I going down the wrong path, or anything?
