Kinetic Energy and Thermal Energy Conversion
A 1500 kg car traveling at 20 m/s is brought to a stop. During the braking process, 80% of the car’s initial kinetic energy is converted to thermal energy in the 10 kg brake system. If the specific heat capacity of the brakes is 500 J/(kg·°C), what is the temperature increase of the brake system?
A
60°C
B
96°C
C
24°C
D
