Part A - Determine its initial angular acceleration.

Part B - Determine the x and y components of reaction at the pin A using scalar notation.

The uniform \( 25-\mathrm{kg} \) plate is released from rest at the Determine its initial angular acceleration. position shown. Express your answer in radians per second squared to three significant figures. Enter positive value if the angular acceleration is clockwise and negative value if the angular acceleration is counterclockwise. Figure 1 of 1 - Part B Determine the \( x \) and \( y \) components of reaction at the pin \( A \) using scalar notation. Express your answers in newtons to three significant figures separated by a comma.
