An ice skater with a weight of 450N is skating at a speed of V=6m/s. Assume the length of the skate blade is L=0.3 m and the width of the blade is W=0.003 m. Suppose the thic kness of the water formed by melting ice by the blade of the skate is h=0.0015mm . The viscosity of water is µ=1.76×10-³(N•s/m²). uy V = 6 m/s 1. Find friction by the skate blade. 2. Find the speed of the skater. h L
