Consider a hammer with a 1.2-kg head. Let it strike the head of a 12-g iron-alloy nail 16 times in a row, quickly. Each time, the hammer head strikes with a speed of 6.5 m/s and is brought to rest. Assuming the nail absorbs all of the hammer head's energy, estimate the temperature rise (in degrees Celsius) of the iron nail. The specific heat of the iron alloy is 450 J/(kg-C).
