A wheel is rotating at a speed of 1000 rpm and its `KE is 10^(6) J`. What is moment of inertia of the wheel about its axis of rotation ?

An autmobile moves on road with a speed of 54 km//h . The radius of its wheel is 0.45 m and the moment of inertia of the wheel about its axis of rotation is 3 kg m^(2) . If the vehicle is brought to rest in 15 s , the magnitude of average torque tansmitted by its brakes to the wheel is :
