Problem: Suppose a piece of dust rests on a CD. The variables to use for the problem are as follows: f = 420 rpm r = 4.1cm t = 2.8min a) If the spin rate of the CD is 420 rpm what distance is traveled by the piece of dust (in radians) in 2.8 mins? b) If the dust is 4.1 cm away from the center, what is the total distance traveled by it during the same time interval in meters?
