A connecting rod is supported by a knife-edge at point \( A \). For small oscillations the angular acceleration of the connecting rod is governed by the relation \( a=-6 \theta \) where \( a \) is expressed in rad/s \( { }^{2} \) and \( \theta \) in radians. The connecting rod is released from rest when \( \theta=14^{\circ} \) Determine the angular position when \( t=2 \mathrm{~s} \). The angular position is
