A Horizontal 2

A 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 forces pushes downward. At the west end of the beam, a 200-N force pushed 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
