A solid balsa cube of side length L = 16.0” and mass M = 8.60 kg is at rest on a horizontal table top. It is constrained to rotate about a fixed and frictionless axis, AB, along one edge of the cube. A bullet of mass m = 50.0 g is fired with speed v at the other side of the cube, at height a = 12.0” above the table surface. The bullet becomes embedded in the cube in the middle of the face opposite face ABCD. Find the minimum value of the speed v required to tip the cube over, so that it falls on face ABCD. You may assume that the bullet mass m is small enough, compared to M, that it does not change the rotational inertia or center of mass of the cube after it embeds. I've been working on this problem for a while and the only answer i got was 921 m/s but i dont think thats right... if someone could help me set up the problem that would be appreciated.
