Physics - Rotation Question with Solution | TestHub

An automobile moves on a road with a speed of$54\mathrm{ }\mathrm{k}\mathrm{m}\mathrm{ }{\mathrm{h}}^{-1}$. The radius of its wheels is$0.45\text{m}$and the moment of inertia of the wheel about its axis of rotation is$3\mathrm{ }\mathrm{k}\mathrm{g}\mathrm{ }{\mathrm{m}}^2$. If the vehicle is brought to rest in$\text{15 s}$, the magnitude of average torque transmitted by its brakes to the wheel is:NEET 2015 (Phase 2)
