Question
A stationary horizontal disc is free to rotate about its axis. When a torque is applied on it, its kinetic energy as a function of $\theta$, where $\theta$ is the angle by which it has rotated, is given as $\mathrm{k} \theta^2$. If its moment of inertia is I then the angular acceleration of the disc is:
