Given
The angular velocity is
[tex]\omega=2.8\text{ rad/s}[/tex]
The time taken,
[tex]t=3.2s[/tex]
To find
The acceleration of the wheel
Explanation
The acceleration is
[tex]\begin{gathered} \alpha=\frac{\omega}{t} \\ \Rightarrow\alpha=\frac{2.8}{3.2}=\frac{0.875rad}{s^2} \end{gathered}[/tex]
Conclusion
The acceleration is
[tex]0.875\text{ rad/s}^2[/tex]
