A .183 kg ball is moving 18.8 m/s when it runs into a spring of spring constant 86.9 N/m. How much KE does the ball have when it has compressed the spring 0.520 m? (Unit=J)

The value is  

Explanation:

From the question we are told that

   The mass of the ball is  

   The initial  speed of the ball is  

    The spring constant is  

     The compression distance is  

Generally the energy stored in the string is mathematically represented as

=>    

=>      

Generally the kinetic energy of the ball is mathematically represented as

=>      

Generally the KE   the ball have when it has compressed the spring is mathematically represented as

=>        

=>        

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
