A block of mass m is kept on a horizontal ruler.Friction coefficient is k.The ruler is kept at one end and the block is at a distance L from the fixed end.The ruler is roated about the fixed end in the horizontal plane thru the fixed end.(a)what can the maximum angular speed be for which the block does not slip.(b) If the angular speed of the ruler is uniformly increased from zero at an angular acceleration a at what angular speed will the block slip..(adsbygoogle = window.adsbygoogle || []).push({});

I've already figured out part (a) please give me some hints as how to work out part (b)
