I need help with this physics problem please show me how to do it the answer is d but i dont know how please show me 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 force 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? \[ I_{\text{beam}} = \left(\frac{1}{3}\right)ML^2 \].Choices:(a) 225 rad/s² (b) 128.57 rad/s² (c) 32.14 rad/s² (d) 8.04 rad/s² (e) 53.57 rad/s² (f) 510.71 rad/s²

We are given a beam which is basically a rod. We are also given formula of moment of inertia of…
