A es004-1.jpginch circular saw blade rotates at 5200 revolutions per minute.
a) Find the angular speed of the saw blade in radians per minute.
b) Find the linear speed in feet per minute of one of the 24 cutting teeth as they contact the wood being cut.

a) angular velocity = 5200(2π) radians/ minute
= appr 3267 radians/min

b) can't make out the radius of the saw blade.

Anyway, do it the same way I just showed you in your previous post
