## Homework Statement

We put a cyllinder with unknown mass and radius 0.1m which rotates with angular velocity 10 /s around its geometric axis on the horizontal ground. After what time does the cyllinder roll without slipping? Coefficient of friction is 0.1.

## Homework Equations

F=ma

M=J ⋅ ∝

## The Attempt at a Solution

J- moment of inertia, k-coefficient of friction ... a* - acceleration of center of mass[/B]

The result should be 2.09 s. Please correct me!
