# Point (A) of the circular disk is at the angular position (theta=0) at time (t=0). The disk

## Question:

Point \(A\) of the circular disk is at the angular position \(\theta=0\) at time \(t=0\). The disk has angular velocity \(\omega_{0}=\) \(0.1 \mathrm{rad} / \mathrm{s}\) at \(t=0\) and subsequently experiences a constant angular acceleration \(\alpha=2 \mathrm{rad} / \mathrm{s}^{2}\). Determine the velocity and acceleration of point \(A\) in terms of fixed \(\mathbf{i}\) and \(\mathbf{j}\) unit vectors at time \(t=1 \mathrm{~s}\).
