An aluminum wheel rubs against an aluminum plate in such a manner that there is a 51.0 N force of kinetic friction between them, and the relative speed at which the two surfaces slide over each other is 43.0 m/s. The specific heat for aluminum is 900 J/(kg C). (a) Determine the rate at which mechanical energy is converted to internal energy (in W). W (b) If the wheel and plate each have a mass of 7.00 kg and they each receive half the internal energy from a 13.0 s run, determine the resultant temperature increase (in C) of each after they have been given time to reach a uniform temperature.
