By defintion, the angular velocity and angular acceleration are the first and second derivative of angular displacement “varphi(t) = 2t^2 – 9t + 4” with respect to time.
Thus, obtain velocity:
“omega (t) = (2t^2 – 9t + 4)’ = 4t – 9”
and acceleration:
“varepsilon(t) = (2t^2 – 9t + 4)” = (4t – 9)’ = 4″
