The 18 kg wheel has a radius of gyration about its center O of ko = 300 mm When the wheel is subjected to the couple moment, it slips as it rolls. Determine the angular acceleration of the wheel and the acceleration of the wheel's center O. The coefficient of kinetic friction between the wheel and the plane is = 0.1. (Figure 1)
