Problem 4: Dice Roll (3 points) A uniform cube rests on a surface that is initially horizontal. We slowly increase the angle of the surface from the horizontal, keeping the cube's bottom face parallel to the surface. At some point, the cube starts moving relative to the surface. When that happens, we see that the cube rolls down rather than slides down the surface. Find the minimum coefficient of static friction / between the cube and the surface. Leave your answer to 3 significant figures
