A yoyo of mass m= 2 kg and moment of inertia I_cm= 0.09 kg m consists of two solid disks of radius R= 0.3 m, connected by a central spindle of radius r= 0.225 m and negligible mass. A light string is coiled around the central spindle. The yoyo is placed upright on a flat rough surface and the string is pulled with a horizontal force F= 24 N, and the yoyo rolls without slipping

Question

A yoyo of mass m= 2 kg and moment of inertia I_cm=   0.09 kg m    consists of two solid disks of radius R= 0.3 m, connected by a central spindle of radius r= 0.225 m and negligible mass. A light string is coiled around the central spindle. The yoyo is placed upright on a flat rough surface and the string is pulled with a horizontal force F= 24 N, and the yoyo rolls without slipping
a)What is the x-component of the acceleration of the center of mass of the yoyo? (in m/s   ) 
b)) What is the x-component of the friction force? (in N)
