A block of mass \(10 \mathrm{~kg}\) and measuring \(250 \mathrm{~mm}\) on each edge is pulled up an inclined surface on which there is a film of SAE \(10 \mathrm{~W}-30\) oil at \(30^{\circ} \mathrm{F}\) (the oil film is \(0.025 \mathrm{~mm}\) thick). Find the steady speed of the block if it is released. If a force of \(75 \mathrm{~N}\) is applied to pull the block up the incline, find the steady speed of the block. If the force is now applied to push the block down the incline, find the steady speed of the block. Assume the velocity distribution in the oil film is linear. The surface is inclined at an angle of \(30^{\circ}\) from the horizontal.
