Un malabarista actua en un recinto cuyo techo est´a 3 m arriba del nivel de sus manos. Lanza una pelota hacia arriba de modo que apenas llega al techo. Calcule:

a) ¿Que velocidad inicial tiene la pelota?
b) ¿Cuanto tiempo tarda la pelota en llegar al techo?
Ahora bien, en el instante en que la primera pelota llega al techo, el malabarista lanza una segunda pelota hacia arriba
con una velocidad inicial de 6 m/s.
c) Cuando han transcurrido 0.4 s desde el lanzamiento de la segunda pelota, ¿a que altura sobre el punto de lanzamiento estan ambas pelotas?
d) ¿A que altura sobre el punto de lanzamiento se cruzan las dos pelotas?

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
