A thin plate is moving vertically between two parallel places wich a constant velocity of 20 m/s. The distance between the boundaries is 0.5 cm and the plate moves at a distance of 0.2 cm from one side of the boundaries. If the area of the plate is 1 m2 and µ, = 0.08 poise, find the weight and mass of the plate.
