I just need a little help getting past the first step. I have already converted rpm to rad/sec.

120 J are done on a fly wheel to raise its speed from 60rpm to 160 rpm. Find its moment of inertia.


How do I convert 120J to power

and how do I set up the inertia half

Think in terms of angular kinetic energy.
