Problem

A rigid disk rotates at a constant angular speed. Three points on the disk are located at radial distances of

0.020\,\text{m}

0.050\,\text{m}

, and

0.080\,\text{m}

from the center. Rank the magnitudes of their linear (tangential) speeds from smallest to largest and briefly state the basis for your ranking.
