A metal block of area 0.10 `m^2` is connected to a 0.010 kg mass via a string that passes over an ideal pulley (considered massless and frictionless), as in Fig. . A liquid with a film thickness of 0.30 mm is placed between the block and the table. When released the block moves to the right with a constant speed of 0.085 m `s^(-1)`. Find the coefficient of viscosity of the liquid.
