**Damon**, Saturday, December 1, 2012 at 9:01pm49 rev/min * 1 min/60 s * 2 pi radians/rev

= 5.13 radians/s

angular acceleration alpha = 5.13 rad/s / 8 s

= .641 radians/s^2

M = torgue or moment = I alpha

= 14.9 * .641 = 9.56 Newton meters

F = M/radius = 9.56/.45 = 21.2 Newtons

so

21.2 = mu * 72

mu = .295
