A sled with two runners slides along a thin horizontal layer ofwater between the ice and the runners. The horizontal force thatthe water puts on the runners is equal to 1.2 lb when the sled'sspeed is 30 ft/s. The total area of both runners in contact withthe water is 0.08 ft2, and the viscosity of the water is3.5x10-5 lb*s/ft2. Determine thethickness of the water layer under the runners. Assume a linearvelocity distribution in the water layer.
