A compact disc stores music in a coded pattern of tinypits 10^ (-7) m deep. the pits are arranged in a track thenspirals outward toward the rim of the disc; the inner and theouter radii of this spiral are 25.0 mm and 58.0 mmrespectively. as the disc spins inside a CD player, the trackis scanned at a constant linear speed of 1.25 m/s

a) What is the angular speed of the CD when scanning theinnermost part of the track? the outtermost part of thetrack?

b) the maximum playing time of a CD is 74.0 minutes. whatwould be the length of the track on such a maximum-duration CD ifit were stretched out in a straight line?

c) what is the average angular acceleration of amaximim-duration CD during its 74.0 minutes playing time? take the direction of rotation of the disc to be positive.
