Identical particles are placed at the 80 cm and 50 cm marks on a meter stick of negligible mass. This rigid body is then mounted so as to rotate freely about a pivot at the 0cm mark on the meter stick. If this body is released from rest in horizontal position, evaluate the angular speed of the meter stick as it swings during its lowest position?
