WILH micion. The block's mass is Mand the rod's length is . A bullet is moving parallel to the table and perpendicular to the rod when it collides and embeds within the block. The bullet's speed just before entering the block is v and its mass is m. (a) Find the angular momentum of the combined bullet-block system about the vertical pivot axis. (Use any variable or symbol stated above as necessary Enter the magnitude.) (b) Find the fraction of the original kinetic energy of the bullet that is converted into intermal energy within the bullet-block system during the collision. (Use any variable or symbol stated above as necessary.)
