In this question, we are asked to calculate the moment of inertia, which is i in order to calculate this moment of inertia. Let me write the relevant equation. Delta k rotational equals to k final minus initial equals to 1 by 2. I omega square minus omega. I square solving this equation, for i we will get. I equals to 2 into delta rotation divided by omega square minus omega square, so call it equation 1. Now setting the values into this equation. We will get. I equals to 2 into minus 500 joule divided by 501 multiplied by 2 pi radiant divided by 60 seconds, whole square, minus 650, multiplied by 2, pi radiant divided by 60 seconds whole square, so this will give us i equals to 0.600 keg meter square. So this is our answer.
