What is the required angular speed of the disk

Reference no: EM13489266

Audio CD players read the data on the disc at a constant linear speed and thus must vary the disc's rotational speed as the reading position moves from the inner edge to the outer edge. The radius of the innermost track is 25 mm and the rotational speed of the disk when the innermost track is read is 8 turns per second.

What is the required angular speed of the disk when the outermost track, whose radius is 58 mm, is read at the same rate as the innermost track?

Angular speed =_________________ rad/s
