 A pendulum in the shape of a rod which has mass $M=4\mathrm{.}62kg$ and length $L=100cm$ is pivoted at point $O$ and initially held in the vertical position as shown in the figure. The rotational inertia of the rod about the center of mass is $I_{CM}=\frac{1}{12}ML2.($Take $g=9\mathrm{.}8\frac{m}{s2}).$ 

 

 

$\mathrm{}\mathrm{}\mathrm{}$$$What is the angular acceleration of the rod when it makes an angle $=29$ with the vertical? Do not forget to encode your answer below:  

 

$\mathrm{}\mathrm{}\mathrm{}$$$Now suppase that the rod is kept in this position and then released $($released from rest at angle $0).$ Determine the angular speed of the rod when it is completely horizontal. Do not forget to encode your answer below:
