The moment of inertia of a uniform-density disk rotating about an axle through its center can be shown to be _ MR. This result is 2 obtained by using integral calculus to add up the contributions of all the atoms in the disk. The factor of 1/2 reflects the fact that some of the atoms are near the center and some are far from the center; the factor of 1/2 is an average of the square distances. A uniform- density disk whose mass is 19 kg and radius is 0. 16 m makes one complete rotation every 0.8 s. Part 1 (a) What is the moment of inertia of this disk? i kg . m2 Save for Later Attempts: 0 of 10 used Submit Answer Part 2 (b) What is its rotational kinetic energy? i Save for Later Attempts: 0 of 10 used Submit Answer Part 3 (c) What is the magnitude of its rotational angular momentum? i kg . m2/s
