A uniform circular disc of radius $\displaystyle 50$ cm at rest is free to turn about an axis which is perpendicular to its plane and passes through its centre. It is subjected to a torque which produces a constant angular acceleration of $\displaystyle 2.0 \mathrm{rad} \mathrm{~s}^{-2}$. Its net acceleration in $\displaystyle \mathrm{ms}^{-2}$ at the end of $\displaystyle 2.0$ s is approximately :
