A carpenter is driving a nail into a board. The 1.25 kg hammer moves at 8.85 m/s when it strikes the nail. Assume half the kinetic energy is transformed into heat in the 15.0 g steel nail and does not flow out. The nail is 3.00 cm long. The specific heat of steel is 448 J/(kg K), and the thermal expansion coefficient is 12x10^-6 K^-1.

A) What is the increase in temperature of the nail after 3 blows from the hammer?

B) What is the change in length of the nail?
