1. The problem statement, all variables and given/known data If you have a rod that is pivoted at one end with a mass of 4 kg and a length of 24 m and the other end has a sphere attached to it that is 4 kg and has a radius of 1.5 m, what is the center of mass? 2. Relevant equations MXcm= m1x1 + m2x2 3. The attempt at a solution I think that the center of mass should be where the sphere attaches to the rod, but I feel like that isn't right.
