A spinning flywheel has a rotational inertia I=400.0 kg metre squared.Its angular velocitydecreases from 20.0rad/secondsto zero in 300.0 seconds due to friction.What is the frictional torque acting?

goodness. See other post
torque = I(moment of inertia) times angular acceleration(change in angular velocity over time) change in angular velocity over time simply put is velocity final - velocity intial divided by total time that's all im doing for you,you should get it form that
