A rod of length 0.50 m and mass 4.0 kg rotates in a horizontal plane about and axis through its center. The rod is at rest when a 3.0 g bullet traveling in the rotational plane is fired into one end of the rod. As viewed from above the bullet's path makes an angle of 60° with the rod. If the bullet lodges in the rod and the angular velocity of the rod is 10 rad/s immediately after the collision, determine the before collision velocity of the bullet. Use conservation of angular momentum. The initial momentum is the point mass momentum of the bullet (the rod is originally at rest). Don't forget to include the bullet when you determine the after collision rotational inertia of the system.
A 4.20 kg cylindrical rod of length 2.00 m is suspended from a horizontal bar so it is free to swing about that end. A solid sphere of mass 0.25 kg is thrown horizontally with a speed v₁ = 17.0 m/s to hit the rod at the point A one-fifth of the way up from the bottom of the rod. The sphere bounces back horizontally with a speed V₂ = 9.50 m/s, while the rod swings to the right through an angle before swinging back toward its original position. What is the angular velocity, in rad/s, of the rod immediately after the collision? rad/s A (a) (b)

The figure shows a small piece of clay colliding into a disk. The disk is initially at rest, but can rotate about a pivot fixed at its center. The collision is completely inelastic.The disk has mass M = 4.84 kilograms and radius R = 0.74 meters. The clay has mass m = 285 grams and is moving horizontally at vi = 3.88 m/s just before colliding with and sticking to the disk. The clay strikes the edge of the disk at a location of b = 0.505 meters offset from the center of the disk. Note that the size of the clay is negligible compared to the radius of the disk. 1. Calculate the angular speed (rad/s) of the disk just after the collision.
In a long jump, an athlete sweeps one of her arm clockwise through 0.5 revolution and the other arm sweeps counterclockwise through 1.0 revolution in 0.7s. Treat each arm as a thin rod of mass 3.0. kg and length 0.5m rotating around one end. In the athlete’s reference frame, calculate the magnitude of the total angular momentum of the arms around the common rotation axis through the shoulders. (given I thin rod = MR^2)
