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