A uniform thin rod of length 0.4 m and mass 0.5 kg can rotate ina horizontal plane about a vertical axis on the left end of therod. The rod is at rest when a 10.0-g bullet traveling in thehorizontal plane of the rod is fired into the right end of the rodat an angle 90o with the rod. The bullet lodges in the rod and theangular velocity of the rod is 10 rad/s immediately after thecollision. The rotational inertia of a rod about axis throughcenter perpendicular to length L is (1/12)*ML2.
Find the rotational inertia of the rod-bullet system when thebullet lodges in the rod. Keep 5 decimal places.
What is the angular momentum after the collision? Keep 4 decimalplaces.
Find the bullet’s initial velocity.
