A uniform solid sphere rolls down an incline. $($a$)$ What must be the incline angle $($deg$)$ if the linear acceleration of the center of the sphere is to have a magnitude of $0\mathrm{.}094$g$?($b$)$ If a frictionless block were to slide down the incline at that angle, would its acceleration magnitude be more than, less than, or equal to $0\mathrm{.}094$g$?$
