1. A computer hard drive typically operates with a rotation speed of 7200 rpm (revolutions per minute). In the first 175 ms the hard drive turns through 4 revolutions at a constant angular acceleration. It continues with that acceleration until it reaches its maximum angular speed.
(i) What is the angular acceleration of the drive, in rad/s2?
(ii) What is the time required for the drive to reach its maximum angular speed, in ms?
(iii) How many total revolutions have been made while the drive is "spinning up" - i.e. reaching its maximum angular speed?
(iv) If the radius of an average hard drive is 3.2 mm, then what is the maximum tangential velocity of the drive?
If linear momentum is conserved when there is no external force applied, how is angular momentum conserved
