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

Jeff was just hired by GSI, Inc. to be their Environmental and Safety Coordinator. This is Jeff's first position after completing his engineering degree. He had taken a course in safety engineering as part of his studies and felt confident that he could handle the job. Management at GSI, Inc. has assured him that they are committed to maintaining a safe workplace. They have never had an individual dedicated to this task full-time. They will implement his recommendations if he can justify them. As Jeff begins to get familiar with the operations, he spends considerable time on the production floor. He notices workers clean their tools before break with a liquid from an unmarked 55-gallon drum. They also use this liquid to clean residue from their skin. They use paper towels to dry their tools and hands, throw these towels in the trash, and head to the break room for a snack and/or smoke. In talking with the workers, Jeff learns of some of their concerns. Several people mention…
