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

2. Relevant equations

Equations of rotational motion

torque = Fdsin(theta)

torque = I (alpha)

v = rw

(alpha) = A_c / r

3. The attempt at a solution

I used the different lengths in simultaneous equations to try and find the different omegas and add them together...but my answer had nothing to do with the question....

I then tried using parallel axis theorem and tried to plug in T = I(alpha) and such to figure out the real torque involved to find alpha and find w finally., and that produced no results.....
