Future space stations will create an artificial gravity by rotating.Consider a cylindrical space station of 380 m diameter rotating about its axis.Astronauts walk on the inside surface of the space station.What rotation period will provide "normal" gravity?

Question

Quizplus · Accepted Answer

To provide "normal" gravity (9.8 m/s²), the centripetal acceleration must equal gravitational acceleration. Using the formula for centripetal acceleration a = (4π²r)/T², where r is the radius (190 m) and solving for T, we find T ≈ 28 s.
