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 of its initial kinetic energy when the block has rotated through the angle * What will be the angular velocity of the block after the bullet emerges? (Ignore gravity in this problem.) Velocity emerging bullet 7 axle S bullet Top View What would be the angular velocity of the block after the bullet emerges if instead of a massless rod, the rod had moment of inertia l about the axle?
