A wooden block of mass m sits on a flat metal table that can be made to oscillate horizontally in simple harmonic motion. The coefficient of static friction between the block and table is . When the table oscillates, the horizontal position x of the block can be expressed as @ Macmillan Learning x (1) = L cos (@t) where L is the amplitude of the oscillation and w is the angular frequency of the oscillation. For a given amplitude, what is the maximum angular frequency @ at which the table can oscillate without the block @
