Physics Problem: Inelastic Rotational Collision with Angular Momentum Conservation

This content explains and solves a physics problem involving an inelastic collision in rotational motion. A uniform rod, pivoted at one end, collides with a putty ball that sticks to its end. The solution demonstrates how to calculate the new moment of inertia of the rod-putty system and then apply the conservation of angular momentum to determine the system's angular speed immediately after the collision
