I really need help with this question!! I can't figure it outno matter what i try: The 1.20 kg head of a hammer has a speed of 6.5 m/s justbefore it strikes a nail and is brought to rest. Estimate thetemperature rise of a 14 g iron nail generated by 10 such hammerblows done in quick succession. Assume the nail absorbs all theenergy. I really need help with this question!!

Explanation / Answer
Remember yourgivens: mass of hammer bread(M) velocity of hammer(V) mass of nail (m) heat of iron(CI) Work it likethis: 10(1/2MV2) =mCIT T=5MV2 mCI Plug in your variables from yourgivens and you should come up with the temperature of the nail.Hope this helps.
