You want to design a large, permanent space station so that no artificial gravity is necessary. You decide to shape it like a large coffee can of radius 223 m and rotate it about its central axis.

a)What rotational speed would be required to simulate gravity? The acceleration of gravity is 9.8 m/s ² .

b) If an astronaut jogged in the direction of the rotation at 5 m/s, what simulated gravitational acceleration would the astronaut feel? Answer in units of m/s ² .

I radius 223 m
