You push a disk$-$shaped platform on its edge $2\mathrm{.}0$ m 

 from the axle. The platform starts at rest and has a rotational acceleration of $0\mathrm{.}33$ rad$/$s$\mathrm{²}$ .

Determine the distance you must run while pushing the platform to increase its speed at the edge to $8\mathrm{.}0$ m$/$s.
