a rod 2.5 m long with mass 10 kg can rotate freely about a horizontal axis through the end of the rod.

a bullet with mass 15 grams or 0.015 kg with a speed of 400 m/s strikes center of the rod in a direction perpendicular to the rod, and is embedded there.

What is the rod's angular speed after the bullet stops in the rod?

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...

A uniform rod of mass 190 g and length 100 cm is free to rotate in a horizontal plane around a fixed vertical axis through its center, perpendicular to its length. Two small beads, each of mass 18 g, are mounted in grooves along the rod. Initially, the two beads are held by catches on opposite sides of the rod's center, 18 cm from the axis of rotation. With the beads in this position, the rod is rotating with an...

A uniform rod of mass 3.40×10−2 kg and length 0.410 m rotates in a horizontal plane about a fixed axis through its center and perpendicular to the rod. Two small rings, each with mass 0.190 kg , are mounted so that they can slide along the rod. They are initially held by catches at positions a distance 5.50×10−2 m on each side from the center of the rod, and the system is rotating at an angular velocity 28.0 rev/min ....

A cylindrical rod of mass 0.82 kg and length 1.88 m is free to rotate about a pivot fixed at one end. A ball with a mass of 3.2 kg is attached to the other end of the rod. The rod-and ball system is held in a horizontal position by a vertical force that acts 1.41 m from the pivot. The force is then removed, and the rod-and-ball swings down. (a) What was the vertical force used to hold the...
