Answer:

ω = 630.2663 = 630[rad/s]

Explanation:

Solution:

- We can tackle this question by simple direct proportion relation between angular speed for the disk to rotate a cycle that constitutes 20 holes. We will use direct relation with number of holes per cycle to compute the revolution per seconds i.e frequency of speed f.

1rev(20 hole) -> 20(cycle)/rev

2006.2(cycle) -> f ?

f = 2006.2/20 = 100.31rev at second

- The relation between angular frequency and angular speed is given by:

ω = 2πf

ω = 2*3.14*100.31

ω = 630.2663 = 630[rad/s]
