En la tierra un volcán puede expulsar rocas verticalmente hasta una altura máxima h. a) ¿a qué altura (en términos de h) llegarían es- tas rocas si un volcán en marte las expulsara con la misma velocidad inicial? la aceleración debida a la gravedad en marte es de 3.71 m> s2, y se puede despreciar la resistencia del aire en ambos planetas. b) si en la tierra las rocas están en el aire un tiempo t, ¿por cuánto tiempo (en términos de t) estarán en el aire en marte?
