A two block system with weights W and Wo is shown above. Wo is pulling W over the table at a steady velocity U. Derive the algebraic expression for this velocity as it slides on a film of oil with a thickness of h and a viscosity . The area in contact with the oil film is the entire bottom of block W and can be represented by the symbol A. You may ignore the weight of the connecting cord and the pulley is frictionless. Assume that the velocity profile in the oil film is linear. W
