A thick 10 kg plate slides down a flat-inclined surface of 20° to the horizontal plane at a terminal speed of 2 m/s. Prior to this, a thin layer of oil was rubbed onto the inclined surface. Provided that the oil viscosity is 0.003 Ns/m². The moving plate has a length of 2 m and a width of 0.5 m. i. Determine the thickness of the oil layer; ii. If the plate should travel at twice the speed, what would the oil layer thickness be?
