That’s really easy ask your teacher and also peace happy
        
             
        
        
        
It depends on how you want to solve it you can solve it in many different meathods:$
        
             
        
        
        
Answer:
The angular  velocity is 
Explanation:
From the question we are told that 
      The mass of each astronauts is  
       The initial  distance between the two  astronauts  
Generally the radius is mathematically represented as 
       The initial  angular velocity is  
        The  distance between the two astronauts after the rope is pulled is 
Generally the radius is mathematically represented as 
 Generally from the law of angular momentum conservation we have that 
            
Here  is the initial moment of inertia of the first astronauts which is equal to
 is the initial moment of inertia of the first astronauts which is equal to  the initial moment of inertia of the second astronauts  So
 the initial moment of inertia of the second astronauts  So
       
Also    is the initial angular velocity of the first astronauts which is equal to
 is the initial angular velocity of the first astronauts which is equal to  the initial angular velocity of the second astronauts  So
 the initial angular velocity of the second astronauts  So
       
Here  is the final moment of inertia of the first astronauts which is equal to
 is the final moment of inertia of the first astronauts which is equal to  the final moment of inertia of the second astronauts  So
 the final moment of inertia of the second astronauts  So
       
Also    is the final angular velocity of the first astronauts which is equal to
 is the final angular velocity of the first astronauts which is equal to  the  final angular velocity of the second astronauts  So
 the  final angular velocity of the second astronauts  So
       
So

I’m pretty sure it just wants you to list the property’s meaning the material and density
