- A disk of radius R=49.4cm rotates about its central axis through O with a constant angular acceleration a=3.29rad/s?, as shown in the figure.

The figure shows multiple solid disks with uniform mass distribution that are spinning about its center. The mass of the disks are the same, but they have different radii, as shown. Rank the disks by the amount of energy needed to spin the disk so that the outer edge of the disk has linear velocity v, from greatest to least. Explain your reasoning. A B C Two students are discussing their previous answer. Student 1: I ranked the largest disk as the greatest amount of energy needed because it has the greatest moment of inertia. Student 2: But, I think we need to also include the angular velocity. Since w=v/r, the angular velocity is smaller for the larger disk and I think all three require the same amount of energy. Do you agree or disagree with either or both of these students? Briefly explain your reasoning.arrow_forward
