Pivoting Rod
A rod with mass M = 1.4 kg and length L = 1.2 m is mounted on a central pivot
.
A metal ball of mass m = 0.7 kg is attached to one end of the rod. You may treat the
metal ball
as a point mass. The system is oriented in the vertical plane and gravity is acting. The
rod initially makes an
angle θ = 27o with respect to the horizontal.
The rod is released from rest.
What is the angular acceleration of the rod immediately after it is released?
