Current Attempt in Progress

A compact disc $($CD$)$ contains music on a spiral track. Music is put onto a CD with the assumption that, during playback, the music will be detected at a constant tangential speed at any point. Since $v_T=r,$ a CD rotates at a smaller angular speed for music near the outer edge and a larger angular speed for music near the inner part of the disc. For music at the outer edge $(r=0\mathrm{.}0568m),$ the angular speed is $3\mathrm{.}95re\frac{v}{s}.$ Find $($a$)$ the constant tangential speed at which music is detected and $($b$)$ the angular speed $($in rev$/$s$)$ for music at a distance of $0\mathrm{.}0211$ m from the center of a CD$.$
