Question

The thin uniform rod has
length 2.0 m and can pivot about a horizontal,
frictionless pin through one end. It is released
from rest at angle u = 40 above the horizontal.
Use the principle of conservation of energy to
determine the angular speed of the rod as it
passes through the horizontal position.
