**Damon**, Wednesday, February 13, 2008 at 7:43pmCentripetal acceleration = w^2 R

where w is angular velocity in radians per second

then the force holding the rider against the wall is m a = m w^2 R

then the maximum friction force preventing a slide to oblivion = 0.47 m w^2 R

when m g is bigger than that we slide

so

9.8 = 0.47 w^2 (4.2)

solve for w

then convert w

w radians/s * (1 rev/2 pi radians) *(60 s/min) = answer in revs/min
