Apendulum is made from a thin cylindrical rod pivoted at the end. it has a length of 0.30 m and radius 0.001 m. it swings up to a max angle. measured from vertical. the angular speed at the bottom of its swing is 2.9 rad/s. what is the max angle in radians?

Maximum angle is rad

Explanation:

As per the question:

length of the pendulum, L = 0.30 m

Radius of the pendulum, R = 0.001 m

Angular speed at the bottom,

Now,

To calculate the maximum angle, :

For the pendulum, the moment of inertia, I =

Now, using the principle of the conservation of energy:

Kinetic energy = Potential energy

where

h =
