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 24 g, are mounted in grooves along the rod. Initially, the two beads are held by catches on opposite sides of the rod's center, 12 cm from the axis of rotation. With the beads in this position, the rod is rotating with an angular velocity of 15.0 rad/s. When the catches are released, the beads slide outward along the rod.

A merry-go-round is a playground ride that consists of a large disk mounted to that it can freely rotate in a horizontal plane. The merry-go-round shown is initially at rest, has a radius R = 1.3 meters, and a mass M = 291 kg. A small boy of mass m = 42 kg runs tangentially to the merry-go-round at a speed of v = 1.8 m/s, and jumps on.
