The Journey of the Solitary Rod

A uniform rod of mass M\displaystyle M and length L\displaystyle L is released from the position as shown. A slight disturbance causes the rod to start its journey to the floor.

When the rod makes an angle θ\displaystyle \theta with the horizontal, find the angular speed of the rod (in rads\displaystyle \frac{rad}{s}), to the nearest integer.

Details and Assumptions:
\bullet The floor is smooth and frictionless.
\bullet M=10Kg\displaystyle M = 10Kg
\bullet L=2m\displaystyle L = 2m
\bullet g=9.8m/s2\displaystyle g = 9.8 m/s^2
\bullet θ=30o\displaystyle \theta = 30^o
