31. (a) The angular speed in rad/s is ω = F H G I K J F H G I K J = 33 1 3 2 60 349 rev / min rad / rev s/min rad / s. π . Consequently, the radial (centripetal) acceleration is (using Eq. 10-23) ar == × = 2 2 2 60 10 .( . . rad / s m) 0.73 m/ s 2 b g (b) Using Ch. 6 methods, we have ma = f s f s , max = μ s mg , which is used to obtain the (minimum allowable) coefficient of friction: s a g ,min . . .. = 073 98 0075 (c) The radial acceleration of the object is a r = 2 r , while the tangential acceleration is
