Rod Mill With High Shell Rotation Speed

A uniform thin rod of length 05 m and mass 40 kg can rotate in a horizontal plane about a vertical axis through its center the rod is at rest when a 30 g bullet traveling the horizontal plane is fired into one end of the rod as viewed from above the direction of the bullet’s velocity makes an angle of 60o with the rod if the bullet lodges.
