A 1.0 kg ball and a 2.0 kg ball are connected by a 1.1-m-long rigid, massless rod. The rod is rotating clockwise about its center of mass at 16 rpm. What torque will bring the balls to a halt in 4.0 s?
Added by Richard F.
Step 1
The moment of inertia for a point mass is given by I = m*r^2, where m is the mass and r is the distance from the axis of rotation. Since the rod is rotating about its center of mass, each ball is at a distance of 0.55 m from the axis of rotation. So, the moment of Show more…
