Answer:
a baseball flying through the air at 90 miles per hour
Explanation:
For the question, Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If the velocity is doubled the kinetic energy will increase by a factor of four.
 
        
                    
             
        
        
        
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
