AYUDA SUPER URGENTE CON ESTE EJERCICIO
Una mujer de masa m está parada en el borde de una mesa giratoria horizontal de momento de inercia I y radio R. La mesa al principio está en reposo y tiene libertad de moverse alrededor de un eje vertical sin fricción que pasa por su centro. La mujer empieza a caminar alrededor de la orilla en direción de las manecillas del reloj (vista desde arriba) a una velocidad constante v en relación a la Tierra.
a) En qué dirección y con qué velocidad angular gira la mesa?
b) Cuál es el trabajo efectuado por la mujer para poner en movimiento la mesa?
