A 1,280 kg car going 27 m/s is brought to a stop using its brakes. Let’s assume that a total of approximately 30 kg of iron in the brakes and wheels absorbs the heat produced by the friction. The car has stopped, what is the change in temperature (in °C) of the brakes and wheels (specific of iron is 460 J/kg oC)? (1.5 points) (b). A 5.0 kg aluminum block falls off a 125 m tall building at a construction site. If all of the potential energy of the block is converted to internal energy in the block as it dropped to the ground, what is the temperature change of the aluminum block? (Assume the specific heat capacity of aluminum is 890 J/kgoC). (1.5 points)
