Homework Help: Heat Transfer of nail into a board

  1. Sep 10, 2009 #1
    1. The problem statement, all variables and given/known data

    A nail driven into a board increases in temperature.

    2. Relevant equations

    If we assume that 60 % of the kinetic energy delivered by a 1.80-\rm kg hammer with a speed of 7.80 \rm m/s is transformed into heat that flows into the nail and does not flow out, what is the temperature increase of an 8.00-\rm g aluminum nail after it is struck ten times?

    3. The attempt at a solution


    60% of 54.756 = 32.8536

    Nail is struck 10 times and moreover is there any heat loss while the nail is being driven!
