En un parque de diversiones, varias personas se divierten en un carrusel de sillas suspendidas por medio de cadenas. Cuando este carrusel se encuentra en funcionamiento, las cadenas que sostienen las sillas forman un ángulo de 25° con la vertical. Si tarda 9 segundos en dar vuelta, calcule
a. La velocidad angular del sistema
b. La velocidad de una silla, si la longitud de cada cadena es de 6 m
c. La tensión en la cadena si en la silla va montada una persona de 48 kg de masa y la silla tiene 9 kg de masa.
