Find the total length of the track

Reference no: EM13557586

A digital audio compact disc carries data along a continuousspiral track from the inner circumference of the disc to theoutside edge. Each bit occupies 0.6 µm of the track. A CDplayer turns the disc to carry the track counterclockwise above alens at a constant speed of 1.18 m/s.

(a) Find the required angular speed at the beginning of the recording where the spiral has a radius of 2.30cm.

rad/s

(b) Find the required angular speed at the end of the recording,where the spiral has a radius of 4.80cm.
