Angular displacement from rotation data

A wheel in a particle accelerator timing run starts at \(3.6\,\text{rad s}^{-1}\) and has angular acceleration \(1.1\,\text{rad s}^{-2}\) for \(10\,\text{s}\). Calculate the angular displacement. Enter the numerical result and choose the interpretation that matches the physics meaning.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
