A uniform thin rod of length 0.51 m and mass 4.2 kg can rotate in a horizontal plane about a vertical axis through its center. The rod is at rest when a 4.8 g bullet traveling in the rotation plane is fired into one end of the rod. As viewed from above, the bullet's path makes angle 0 = 60° with the rod. If the bullet lodges in the rod and the angular velocity of the rod is 12.0 rad/s immediately after the collision, what is the bullet's speed just before impact? %3D Axis -
