One complete revolution is 2 pi radians.
The earth revolves one complete revolution in 24 hours.
24 hours * 60 min/1 hr * 60 sec/1 min = 86400 seconds
The earth revolves at a rate of (2*pi)/86400 rad/sec = 7.27 e -5 rad/sec = w
r = radius of curvature = radius of the earth. 6378100 meters
angular acceleration = w^2* r
angular acceleration = (7.27 e -5)^2* 6378100 = 0.03373 m/s/s
