Homework Statement
A 240g ball and a 570g ball are connected by a 48.0-cm-long massless, rigid rod. The structure rotates about its center of mass at 110 rpm.
Homework Equations
KE = Iω^2
I = 1/12(mr^2)
The Attempt at a Solution
Since it has two masses and two different radius, I was not sure with what I should've done.
