The uniform 22-kg plate is released from rest at the position shown. (Figure 1) Figure A 0.5 m 1 of 1 0.5 m Determine its initial angular acceleration. 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. V—| ΑΣΦ | | | vec α = Submit Part B Request Answer ? D rad/s² 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.
