大家好,歡迎來到Yogi霸霸解題給你看,今天我要講解的是AP Physics C裡Rotation的作業。

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 = 0.010 kg · m2 and IB = 0.910 kg · m2. What is the mass of the disk?
