understood how to solve it but why cant we use tota hange in momentum total time to calculate avg torque tried it that way but ans was wrong An automobile moves on a road with a speed of 54 kmh 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 m If the vehicle is brought to rest in 15 s the magnitude of average torque transmitted by its brakes to the wheel is 1 6 66 kg m s 2 8 58 kg m s 2 3 10 86 kg m s 4 2 86 kg m s 2
