## Celmusa 2 years ago A disc of moment of inertia I=125KG.m squared is rotating with angular velocity of 90rad/s and is brought in contact with a stationary dic of moment of inertia I2= 80kg.m squared such that their axis of rotation coincide. find the final angular velocity reached by the two discs?

consevarion of angular momentum$I_{1} \omega_{1} = I_{1} \omega_{2} + I_{2} \omega_{2}$
