(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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?

2. Relevant equations

tried looking at the angular velocity/displacement/acceleraions equations but i dont know how to even begin this question.

3. The attempt at a solution

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