It is proposed that future space stations create an artificial gravity by rotating. Suppose a space station is constructed as a 800-m-diameter cylinder that rotates about its axis. The inside surface is the deck of the space station. Part A What rotation period will provide "normal" gravity? Express your answer with the appropriate units. View Available Hint(s)
