You shove a cube of inertia m and side length d so that it s

You shove a cube of inertia m and side length d so that it slides along a smooth table with speed v_i (Figure a). The cube then hits a raised lip at the end of the table. After it hits the lip, the block begins to rotate about it (Figure b). (a) Show that the magnitude of the block%u2019s angular mo- mentum about the lip before the collision is L = mdv_i/2. (b) Explain why the angular momentum still has that value at the instant of collision, before the block has had time to rotate much. (c) What is the rotational acceleration of the block the instant after it hits the lip? (d) What maximum initial speed can the block have so that it does not topple over the lip?
