A female freestyle ice skater, weighing \(100 \mathrm{lbf}\), glides on one skate at speed \(V=20 \mathrm{ft} / \mathrm{s}\). Her weight is supported by a thin film of liquid water melted from the ice by the pressure of the skate blade. Assume the blade is \(L=11.5\) in. long and \(w=0.125\) in. wide, and that the water film is \(h=0.0000575\) in. thick. Estimate the deceleration of the skater that results from viscous shear in the water film, if end effects are neglected.
