Homework Statement
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?
Homework Equations
Equations of rotational motion
torque = Fdsin(theta)
torque = I (alpha)
v = rw
(alpha) = A_c / r
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...
