Question 10

During a dynamometer test of a high-performance vehicle, the friction from braking supplies 234 kJ of thermal energy to a carbon-silicon carbide brake rotor.

The rotor has a mass of 1.2 kg.

The specific heat capacity of this carbon-silicon carbide composite is 650 J/kg ∘C650\text{ J/kg }^\circ\text{C}650 J/kg ∘C.

Calculate the temperature increase of the brake rotor during this test.
