Re: [Phys-l] friction

This is such a complicated situation given variations in temperature,  
pressure on the ice, and the water at the interface, I don't think  
you will find a value that is much good for anything.  Most  
coefficients are for dry surfaces just because the liquid interface,  
ie lubrication complicates matters enormously.
