## Homework Statement

a wheel rotates with a constant angular acceleration pie rad/s^2. during a certain time interval its angular displacement is pie rad. at the end of the interval its angular velocity is 2pie rad/s. what is the angular velocity at the beginning of the interval?

## Homework Equations

tried looking at the angular velocity/displacement/acceleraions equations but i don't know how to even begin this question.

## The Attempt at a Solution

well i have to find the initial angular velocity and the time interval is also unknown.
