12. We assume the sense of rotation is positive, which (since it starts from rest) means all quantities (angular displacements, accelerations, etc.) are positive-valued. (a) The angular acceleration satisfies Eq. 10-13: 22 1 25 rad (5.0 s) 2.0 rad/s . 2 αα = ¡ = (b) The average angular velocity is given by Eq. 10-5: ω θ avg rad 5.0 s rad / s. == = Δ Δ t 25 50 . (c) Using Eq. 10-12, the instantaneous angular velocity at
