A ballerina begins a tour jete, (Figure) with angular speed ai and a rotational inertia consisting of two parts: Ileg = 1.44 kg ∙ m2 for her leg extended outward at angle θ = 90.0° to her body and Itrunk = 0.660 kg ∙ m2 for the rest of her body (primarily her trunk). Near her maximum height she holds both legs at angle θ = 30.0° to her body and has angular speed wy (Figure). Assuming that Itrunk has not changed, what is the ratio wf/wy?
