The angular displacement, \(\theta\) radians, of the spoke of a wheel is given by the expression \(\theta = 1.1t^3 - t^2\), where \(t\) is the time in seconds.
The angular velocity after 3 seconds \((\omega_3)\).
\(\omega_3 = \boxed{\qquad} \text{ rad/sec}
The angular acceleration \((\alpha_2)\) after 2 seconds
\(\alpha_2 = \boxed{\qquad} \text{ rad/sec}^2\)
