9. A uniform rod (length =2.0 m) with a mass of 1.00kg has a 2.0-kg point mass attached to one end. The rod is mounted to rotate freely about a horizontal axis that is perpendicular to the rod and that passes through a point 1.50m from the point mass. The rod is released from rest when it is horizontal. What is the angular velocity of the rod at the instant the 2.0-kg mass passes through its low point? a. 1.7 rad/s b. 2.6 rad/s 4.0 rad/s 5.0 rad/s с. d. e. 3.7 rad/s
