Changes in Temperature & Heat Capacity Video Lessons

# Problem: A 6.5 g alumin nail is being hammered into a piece of wood. If 50% of the kinetic energy of a 1.5 kg hammer is transferred to the nail with each strike, and all of the kinetic energy carried by the nail transformed into heat as it travels through the wood, how much does the temperature of the nail rise after being struck 5 times? Consider the hammer striking the nail at a speed of 5 m/s each time. Note that the specific heat of aluminum is 0.9 J/gK.
