A spaceship has a rotating compartment which gives its passengers artificial gravity.
Suppose this compartment is a cylinder with a radius of 10.7 m. In order for the
artificial gravity to be the same strength as what is experienced on Earth's surface,
what would the period of rotation of this compartment need to be, in seconds?
