Una caja de 25 kg se mueve durante 10 s. sobre una superficie horizontal , sin rozamiento a partir del reposo hasta alcanzar una velocidad de 50 cm/s ¿cuál es la magnitud de la fuerza neta que actúa sobre dicha caja?

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?
