A female freestyle ice skater, weighing 100 lbf, glides on one skate at speed V = 20 ft/s. Her weight is supported by a thin
lm 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 lm is h = 0.0000575 in. thick. Estimate the deceleration of the skater that results from
viscous shear in the water lm, if end effects are neglecte
