Constant velocity means the netto force = 0, therefore F(gravity) = F(astronaut).
175N divided by 87,5kg = 2.00kg/N
        
                    
             
        
        
        
| Impedance | = √ [R² +(ωL)²]
R² = 6800² = 4.624 x 10⁷
  
(ωL)² = (2 · π · f · 2.3 · 10⁻³)² 
          = 2.0884 x 10⁻⁴  f²
| Z | =  √[ (4.624 x 10⁷) + (2.0884 x 10⁻⁴ f²) ]  =  1.6 x 10⁵
     (1.6 x 10⁵)²  =  (4.624 x 10⁷) + (2.0884 x 10⁻⁴ f²) 
     (2.56 x 10¹⁰) - (4.624 x 10⁷)  =  2.0884 x 10⁻⁴ f² 
Frequency² =   (2.56 x 10¹⁰ - 4.624 x 10⁷)  /  2.0884 x 10⁻⁴ 
                    =       2.555 x 10¹⁰ / 2.0884 x 10⁻⁴
                    =          1.224 x 10¹⁴  
                    =          122,400 GHz          <== my calculation
                                      11.1 MHz           <== online impedance calculator
Obviously, I must have picked up some rounding errors 
in the course of my calculation.  
   
        
             
        
        
        
Answer:
ω = 0.05 rad/s
Explanation:
We consider the centripetal force acting as the weight force on the surface of the cylinder. Therefore,

where,
ω = angular velocity of cylinder = ?
g = required acceleration = 9.8 m/s²
r = radius of cylinder = diameter/2 = 5.9 mi/2 = 2.95 mi = 4023.36 m
Therefore,

<u>ω = 0.05 rad/s</u>

This question is personal preference... just answer with whatever YOU think, there probably isn’t s wrong answer if I’d guess.
