A block of mass m = 20 kg is kept is a distance R = 1m from central axis of rotation of a round turn table (A table whose surface can rotate about central axis). Table starts from rest and rotates with constant angular acceleration, `alpha = 3 rad//sec^(2)`. The friction coefficient between block and table is `mu = 0.5`. At time `t = (x)/(30)` from starting of motion (i.e. t =0) the block is just about to slip. Find the value of x `(g = 10 m//s^(2))`
