Question 32

During one stop, energy is transferred to a set of steel brake discs. The total mass of the discs is 10.0 kg.

QuantityValue
Energy transferred to the discs1.84 × 105 J
Specific heat capacity of the steel460 J/kg ∘C460\ \text{J/kg}\ ^{\circ}\text{C}460 J/kg ∘C

Use the equation

ΔQ=m×c×Δθ\Delta Q = m \times c \times \Delta \thetaΔQ=m×c×Δθ

Calculate how much the temperature of the discs increases during this stop.
