Question

FIGURE 3 shows an ice skater has a movement of inertia of 4 kg m$^2$ when her arms wrap her body and 16 kg m$^2$ when her arms are stretched. When the two arms are pressed against her body, the speed of the skater's rotation is 12 rotations per second. If then the arms are stretched, how much the rotation speed becomes?
