2. (25 points) A vertical axle is free to rotate. A massless rod of length S is attached to the axle, as shown, and a small wooden block of mass mi is attached to the rod. A bullet, mass m2, is shot at the block with velocity of magnitude vi at the angle o as shown. The bullet slows down inside the block, finally coming out in the direction shown with į of its initial kinetic energy when the block has rotated through the angle 2. What will be the angular velocity of the block after the bullet emerges?
