A dumbbell consists of a slender rod of negligible mass and small spheres attached to each end with mass 1-kg and 2-kg respectively. It is pivoted at its center about a fixed horizontal frictionless axle and initially held in place horizontally. The length of the rod is 1 meter and connects the centers of the two spheres. The dumbell is then released.
8) What is the magnitude of angular acceleration immediately upon release?
so i first find the center of mass, the vertical acceleration is 9.8 m/s^2 upon release, and i just use the formulas to figure this out
is that the correct way to do this?
my friend said this had somethin to do with inertia... i'm not sure... help pleaseeee
