Overhead view of the rod-projectile system before collision.
A uniform thin rod of mass \(M\) and length \(L\) lies at rest on a frictionless horizontal table and is attached to a frictionless vertical pivot at one end. A small projectile of mass \(m\) moves horizontally across the table with constant speed \(v_0\) along a path perpendicular to the rod and strikes the free end, becoming permanently embedded in it. In the limit where the projectile is extremely massive compared to the rod (\(m \gg M\)), what is the angular speed of the system immediately after the collision?
