A small block starts slipping down from a point B on an inclined plane 
which is making an angle 
with the horizontal section 
is smooth and the remaining section 
is rough with a coefficient of friction 
It is found that the block comes to rest as it reaches the bottom (point 
) of the inclined plane. If 
, the coefficient of friction is given by 
.The value of k is _________.
