Problem

A spool has an inner hub of radius

0.040\,\text{m}

and an outer rim of radius

0.10\,\text{m}

. A tape is wrapped around the hub and pulled straight upward at a constant speed of

0.50\,\text{m/s}

. If the spool rolls without slipping on a horizontal surface, what is the speed of the spool’s center of mass? a)

0.50\,\text{m/s}

2.0\,\text{m/s}

1.25\,\text{m/s}

0.20\,\text{m/s}
