Question

A typical hard disk in a desktop computer is a uniformly solid, 400 gram disk 3.5 inches in diameter, and takes 70 milliseconds to spin from rest up to a frequency of 7200 revolutions per minute (r.p.m.).

Problem 2.4. How many revolutions does the disk go through during this spin-up process?

Problem 2.5. Which is bigger, the centripetal force felt by a dust particle stuck to the edge of the disk halfway through its spin-up or the centripetal force felt by an identical dust particle stuck halfway to the edge of the disk when it’s at full speed?
