A nail driven into a board increases in temperature. If 60% of the kinetic energy delivered by a 1.8 kg hammer with a speed of 7.8 m/s is transformed into heat that flows into the nail and does not flow out, what is the increase in temperature of an 8 g aluminum (c = 900 J/(kg • C°)) nail after it is struck 10 times
