a thin cylinderical shell of inner radius 1.5 m rotates horizontally about a vertical axis at an angular speed omega . A wooden blocks rests against the inner surface and rotates with it . if the coefficient of static friction between the block and surface is 0.3 how fast must the she'll be rotating if the block is not to slip and fall
