A car moves on a road with a speed of `54 km h^(-1)`. The radius of its wheels is `0.35 m`. What is the average negative torque transmitted by its brakes to the wheels if the car is brought to rest in `15 s`? Moment of inertia of the wheels about the axis of rotation is `3 kg m^(2)`.

An automobile moves on a road with a speed of 54 km/h. The radius of its wheels is 0.35 m. What is the average negative torque transmitted by its brakes to a wheel if the vehicle is brought to rest in 15 s? The moment of inertia of the wheel about its axis of rotation is 3 kg- m^(2) .

An automobile moves on a road with a speed of 54 km h^-1 . The radius of its wheels is 0.45 m and the moment of inertia of the wheel about its aXIIs of rotation is 3 kg m^2 . If the vehicle is brought to rest in 15s, the magnitude of average torque transmitted by its brakes to the wheel is
