Problem

A solid disk of mass

0.50\,\text{kg}

and radius

0.10\,\text{m}

is spinning about its central axis. A

0.20\,\text{kg}

blob of clay sticks to the rim of the disk, after which the combined system rotates together at

8.0\,\text{rad/s}

. Determine the magnitude of the angular momentum of the disk–clay system about the center of the disk immediately after the clay sticks.
