Rotational dynamics about a fixed axis: A very thin horizontal, 2.00-m long, 5.00-kg uniform beam that lies along the east-west direction is acted on by two forces. At the east end of the beam, a 200-N force pushes downward. At the west end of the beam, a 200-N force pushes upward. What is the angular acceleration of the beam? A) 240 rad/s² north B) 1.33 × 10² rad/s² north C) zero D) 240 rad/s² south E) 1.33 × 10² rad/s² south
