A ballerina begins a tour jete with angular speed ?i and a rotational inertia consisting of two parts: Ileg = 1.55 kg*m^2 for her leg extended outward at angle ? = 90.0 to her body and Itrunk = 0.518 kg*m^2 for the rest of her body (primarily her trunk). Near her maximum height she holds both legs at angle ? = 33.5 to her body and has angular speed ?f. Assuming that Itrunk has not changed, what is the ratio ?f/?i?
