With the aid of a string, a gyroscope is accelerated from rest to \( 17 \mathrm{rad} / \mathrm{s} \) in \( 0.42 \mathrm{~s} \). (a) What is its angular acceleration in \( \mathrm{rad} / \mathrm{s}^{2} \) ? \[ \mathrm{rad} / \mathrm{s}^{2} \] (b) How many revolutions does it go through in the process? rev
