A uniform circular disc of radius \( 50 \mathrm{~cm} \) 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 \( 2.0 \mathrm{rad} \mathrm{s}^{-2} \). Its net acceleration in \( \mathrm{ms}^{-2} \) at the end of \( 2.0 \mathrm{~s} \) is approximately
