a) By modelling the ballerina with her arms and legs tucked in as a uniform eylinder of mass 60kg and radius 13em, find her angular momentum after she has tucked her arms in. The moment of inertia of a uniform eylinder of mass M and radius R is given by I = ¿MR b) Hence, estimate her moment of inertia with respect to her axis of rotation when her arms and legs were outstretched.
