A 73.9 kg shaft with a radius of 8.9 cm is spinning at a rate of 364.5 rpm. If a board leans against the outside providing a frictional force of 59.92 N, how long will it take for the shaft to stop rotating?(adsbygoogle = window.adsbygoogle || []).push({});

Answer says 2.094 s.

Problem I have is that my Inertia table doesn't list shaft inertia or anything. Unsure how to go about starting this?
