I know I1ω1=I2ω2 And that the total angular momentum of a system is conserved, i.e. remains constant. Is that where you're leading me? :)

Homework Statement A constant torque of 25.5 N · m is applied to a grindstone whose moment of inertia is 0.117 kg · m2. Using energy principles, and neglecting friction, find the angular speed after the grind- stone has made 14.6 rev. Answer in units of rad/s Homework Equations 1...
