In astrophysics, a spinning sphere of gas can flatten out to form a disk. During this process, the system angular momentum is conserved. Let the mass of the gas sphere be M, its radius be R, and its angular velocity be a. See before figure. After flattening to a 7 disk, the radius is R. See after figure. What is the new angular velocity when it is a 2 disk? You may assume that there is no loss in mass during this process. The knowns are M, R and @. (10 points) axis axis 7/2 R R @ before solid sphere about diameter 00,=? after disk about its axis
