The CD-ROM drive in a computer accelerates a disk from rest to its full speed of 20000 revolutions per minute; it does so uniformly over 5 seconds. The disk is 6 cm in radius.(a) Is it correct to write ? = 4000 rev min?1 s?1? Explain.(b) What is the maximum angular velocity in our conventional units of radians per second?(c) What is its angular acceleration?(d) How many times does it spin during this interval?(e) After four seconds, what is the tangential velocity of a point along the edge of the disk? (f) After four seconds, what is the angular velocity of a point along the edge of the disk?(g) After four seconds, how many times has the disc rotated?
