A space station has a diameter of 1000 ft (300 m) and to rotate at a rate sufficient to cause occupants in the outer rings to experience a centripetal force roughly equal to the gravitational force of the moon(1.622m/s^2)
(a) what is the approximate speed in m/s of the outer rim of the ring?
(b) what is the centripetal acceleration that a person in the rim of the wheel would experience.
A 50 g Super Ball travelling at 28 m/s bounces off a brick wall and rebounds at 18 m/s. A high-speed camera records this event. If the ball is in contact with wall for 5 ms, what is the magnitude of the average acceleration of the ball throughout ..
