1. The problem statement, all variables and given/known data Consider a solid hemisphere of uniform density with radius R. Where is the center of mass? z=0 0 z R 2 z=R 2 R 2 z r z=R Image is provided. 2. Relevant equations None 3. The attempt at a solution Answer A and E do not seem logical. I thought it was answer C from my eyes. Center of mass is the average of the masses factored by their distances from a reference point. I didn't think the answer could range like B and D do.
