Cuando el estudiante mantiene extendidos sus brazos horizontalmente, los objetos distan a 1.0 m respecto al eje de rotación y éste gira con una rapidez angular de 0.75 rad/s; el momento de inercia del estudiante y la silla, tienen y una magnitud constante de 3 kg .m². Suponiendo que el estudiante jalará los objetos horizontalmente a 0.30 m del eje de rotación, determinar: a) La nueva rapidez angular del estudiante. b) La energía cinética del estudiante antes y después de que los objetos sean aproximados al eje de rotación
