A nonuniform 2.0-kg rod is 2.0 m long. The rod is mounted to rotate freely about a horizontal axis perpendicular to the rod that passes through one end of the rod. The rotational inertia of the rod about this axis is 4.0 kg⋅m². The center of mass of the rod is 1.2 m from the axis. If the rod is released from rest in the horizontal position, what is its angular speed as it swings through the vertical position? A)3.4 rad/s B)4.4 rad/s C)4.3 rad/s D)5.8 rad/s E)6.8 rad/s
