A horizontal 4.00-m long, 7.00-kg uniform beam that lies along the east-west direction is acted on by two forces. At the east end of the beam, a 300-N forces pushes downward. At the west end of the beam, a 400-N force pushes upward. What is the angular acceleration of the beam about an axis that passes through the west end? [Ibeam (1/3)ML]. (a) 225 rad/s². (d) 8.04 rad/s². (b) 128.57 rad/s². (e) 53.57 rad/s². (c) 32.14 rad/s (f) 510.71 rad/s².
