**Question **# A ball of mass M and radius R rolls smoothly from rest, at initial height h, down the above ramp and onto a circular loop of radius r. At the loop bottom, the magnitude of the normal force on the ball is N = 2M g.This ball, however, has nonuniform mass density, as it consists of an outer spherical shell and an inner sphere, each of different uniform mass densities. This results in I = BMR? where 3 + 2/5. What is 3 for our ball? (10 pt)
