QUESTION:

The 300-kg wheel has a radius of gyration about its mass center O of \(k_{O} = 400 \ mm\). If the wheel is subjected to a couple moment of \(M=300 \ \mathrm{N} \cdot \mathrm{m}\), determine its angular velocity 6 s after it starts from rest and no slipping occurs. Also, determine the friction force that the ground applies to the wheel.
