A disc is rotating with angular velocity omega . If a child sits on it, what is conserved?

A disc is rotating with angular velocity omega . If a child sits on it, what is conserved?

A disc rotates with angular velocity omega and kinetic energy E . Then its angular momentum

A disc is rotaing with an angular velocity omega_(0) . A constant retarding torque is applied on it to stop the disc. The angular velocity becomes (omega_(0))/(2) after n rotations. How many more rotations will it make before coming to rest ?
