Figure (a) shows a disk that can rotate about an axis at a radial distance h from the center of the disk. Figure (b) gives the rotational inertia I of the disk about the axis as a function of that distance h, from the center out to the edge of the disk. The scale on the I axis is set by IA = 0.050 kg-m2 and IB = 0.150 kg-m2. What is the mass of the disk?

Ip Axis 0.1 h (m) 0.2 (a) (b) I (kg m2)
