3\,\text{rad}\,\text{s}^{-2}

. At an instant when its angular velocity is

12\,\text{rad}\,\text{s}^{-1}

, consider a point

Q

on its rim

0.25\,\text{m}

from the axis. (i) Calculate the magnitudes of the tangential and centripetal components of the linear acceleration of

Q

at that instant. (ii) Determine the magnitude of the resultant linear acceleration of

Q

at the same instant. (iii) Find the angle that the resultant acceleration makes with the tangential direction at this instant.
