For the conditions of Sample Problem 5/17, determine the angular acceleration of \(A C\) and the acceleration of \(A\) relative to the rotating slot in \(\operatorname{arm} O D\).

Problem 5/17,

The pin \(A\) of the hinged link \(A C\) is confined to move in the rotating slot of link \(O D\). The angular velocity of \(O D\) is \(\omega=2 \mathrm{rad} / \mathrm{s}\) clockwise and is constant for the interval of motion concerned. For the position where \(\theta=45^{\circ}\) with \(A C\) horizontal, determine the velocity of pin \(A\) and the velocity of \(A\) relative to the rotating slot in \(O D\).
