1. The problem statement, all variables and given/known data A 1.2kg ball and a 2.2kg ball are connected by a 1.0m long rigid, massless rod. The rod is rotating clockwise about its center of mass at 26rpm. What torque will bring the balls to a halt in 5.6s? 2. Relevant equations T = I(alpha) Wf = Wi + alpha (delta t) I = m1(r1^2) + m2(r2^2) 3. The attempt at a solution I tried finding I = (1.2kg)(.5m)^2 + (2.2kg)(.5m)^2 = .85. Then I tried using Wf = Wi + alpha(delta t) to find alpha, which I got to be -.829. Then I tried using T = I(alpha) and I got -7.047, but it was wrong.
