A uniform rod (length = 2.4 m) of negligible mass has a 1.0-kg point mass attached to one end and a 2.0-kg point mass attached to the other end. The rod is mounted to rotate freely about a horizontal axis that is perpendicular to the rod and that passes through a point 1.0 m from the 2.0-kg 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. 2.2 rad/s C. 2.0 rad/s D. 1.5 rad/s E. 3.1 rad/s
What must be exerted on an object to change the angular momentum?
