## Homework Statement

Question: A circular cylinder with mass of 1 kg and radius a=0.1 m is rotating about its cylindrical axis at a rate of 5 revolutions per second. It is then placed on a flat surface. Assuming that there is no dissipation at contact and the cylinder is rolling without slipping (with negligible rolling friction) on the flat surface, its translational speed is:

## Homework Equations

v=rω

## The Attempt at a Solution

v=0.1 (5*2π)=π m/s

The answer is 1.81m/s. Can anyone help?
