An automobile moves on a road with a speed of 54 km h−154\ \text{km h}^{-1}. The radius of its wheels is 0.45 m and the moment of inertia of the wheel about its axis of rotation is 3 kg m23\ \text{kg m}^2. If the vehicle is brought to rest in 15 s the magnitude of average torque transmitted by its brakes to the wheel is 10.86 kg m2 s−210.86\ \text{kg m}^2\ \text{s}^{-2} 2.86 kg m2 s−22.86\ \text{kg m}^2\ \text{s}^{-2} 6.66 kg m2 s−26.66\ \text{kg m}^2\ \text{s}^{-2} 8.58 kg m2 s−28.58\ \text{kg m}^2\ \text{s}^{-2}
