The angle through which a rotating wheel has turned in time t is given by \(adsbygoogle = window.adsbygoogle || []).push({});

theta = a t - b t^2+ c t^4, where theta is in radians and t in seconds.

What is the average angular velocity between t = 2.0 s and t =3.3 s?

If a = 9.0 rad/s, b = 16.0 rad/s^2, c = 1.6 rad/s^4

2. Relevant equations

d(theta)/dt = omega

omega average = change in theta / change in time

3. The attempt at a solution

omega =a-2bt+4ct^3

i got omega = 63.1 rad/s (omega =a-2bt+4ct^3 )

and 2nd time i got 19.0826 (change in theta / change in time)

both is wrong when i put on the webs

can anyone help me please
