13.40:An ideal uniform soli
0 fwz/t7 pwl 4p/c2mykd disk and an ideal uniform ring each have mass M and radius R. Each object begins purely rolling witho
tyc lwz p0k//wp4f2 m7ut slipping down a rough inclined plane. The coefficients of friction for the disk and ring with the incline are $μ_disk> μ_ring$.
As the objects roll, what is the ratio of the ring’s angular acceleration to the disk’s angular acceleration calculated about an axis perpendicular to the object’s face and through its center of mass?
