A thin 1 m long uniform rod with a total mass of 750g is suspended vertically at the upper end. The moment of inertia of the rod in respect to the center of mass is mL*2/12 (where L is the total lenght of the rod). A 9 g bullet is shot to the lower end of the rod and embeds there. The bullet speed before impact is 580 m/s. Calculate the amount of energy transfered to the heat during the collision.

A uniform stick 1.0 m long with a total mass of 300.0 g is pivoted at its center. A 3.0 g bullet is shot through the stick midway between the pivot and one end. The bullet approaches at 250 m/s and leaves at 160 m/s. With what angular speed is the stick spinning after the collision, if the bullet strikes the stick perpendicularly? (The moment of inertia of a uniform stick rotating about its center is I = (1/12)mL2.)

A uniform thin rod of length 0.56 m and mass 3.2 kg can rotate in a horizontal plane about a vertical axis through its center. The rod is at rest when a 3.5 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 θ = 60° with the rod. If the bullet lodges in the rod and the angular velocity of the rod is 12.0 rad/s...
