Problem

A cylindrical space station is designed so that people walking on its inner surface experience an apparent weight equal to

0.80

of their normal Earth weight. If the station’s living ring has a radius of

50\,\text{m}

, what should be the rotation period of the station? (a)

22\,\text{s}

(b)

14\,\text{s}

(c)

16\,\text{s}

(d)

32\,\text{s}
