Answer:
Total length of spring 0.647 m 
Explanation:
We have given mass of the person m = 150 kg 
Acceleration due to gravity 
Spring constant k = 10000 N/m
Nominal length of spring = 0.50
According to hook's law 


x = 0.147 m
So total length of spring = 0.50+0.147 = 0.647 m
 
        
             
        
        
        
The answer is D interferometry
