Aprojectile is shot upward from the surface of earth with an initial velocity of 96 meters per second. use the position function below for free-falling objects. what is its velocity after 5 seconds? after 10 seconds? (round your answers to one decimal place.)

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?
