Please answer correctly. Use Force-Mass-Acceleration Method. A 0.25-kg hollow square thin plate is pin-connected to a wall with an outer side length of c = 15 cm and an inner side length of b = 13 cm. At the instant shown, the plate is subjected to a vertical force of P = 5 N (at the outermost corner), with a clockwise angular velocity of ω = 10.888 rad/s. Determine the (a) angular acceleration of the plate, and the (b) horizontal and vertical reactions at pin O.
