Problem 2. A copper cube with a side length of 250mm is sliding down an incline on a 10mu m thick film of oil. The angle of inclination is alpha =15deg . Given that the density of copper (
ho _(copper ))=(8.96(g)/(c)m^(3)) and the dynamic viscosity of the oil (mu _(oil ))=(7mPa*s), what is the terminal velocity of the copper block once the sliding motion has reached steady state?
