**drwls**, Sunday, October 24, 2010 at 12:38pmw = a*t where a is the angular acceleration, in rad/s^2, and t is the time since it started to accelerate

R w^2 = R*(a*t)^2 = 2 R*a

R cancels out. a^2* t^2 = 2a

t = sqrt (2/a)

I cannot provide a numerical value without knowing the acceleration rate.
