The gravitation acceleration on the moon is different than on Earth. It is 1.6 m/s^2. If you weigh 120 lbs, then you would multiply 120 pounds by the gravitational acceleration on the moon and then divide by the acceleration on Earth. 
(120 lbs * 1.6) / 9.8 = 20 pounds. 
The mass will always be the same no matter what planet you’re on, so it’s still 54 kg.
        
             
        
        
        
An airplane has a large amount of kinetic energy in flight due to its large mass and fast velocity. 
 
        
             
        
        
        
Answer:
The  velocity is  
Explanation:
From the question we are told that 
    The  mass of the bullet is  
     The initial speed of the bullet is  
    The mass of the target is  
     The  initial velocity of target is  
     The  final velocity of the bullet is  is  
     
Generally according to the law of momentum conservation we have that 
       
=>   
=>
