Un objeto A de masa 4 Kg se mueve en la dirección positiva de eje X con una velocidad de 8 m. S-1, choca con otro objeto B de masa 6 Kg que estaba en reposo. Después del choque A se desvía 40º al Sureste con una velocidad de 4 m. S-1. Calcular el módulo y dirección de la velocidad de B después del choque. 4 points

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?
