The first step is to set up the calculation to stop the supply spacecraft from spinning. The first part of the problem is determining the proper moment of inertia calculation. The rocket is the shape of a cylinder with mass $=m$ and radius $=r.$ Assume the supply shuttle is rotating as if it were a cylinder rotating about it's center axis perpendicular to the circular sides. What is the equation for the moment of inertia for the rotating space station?

$I=m{r}^2$

$I=\frac{1}{2}(mr{)}^2$

$I=\frac{1}{2}m{r}^2$

$I=\frac{1}{2}mr$
