Answer:
![X_2 = 0.122m](https://tex.z-dn.net/?f=X_2%20%3D%200.122m)
Explanation:
Using the law of the convervation of energy E:
![E_i = E_f](https://tex.z-dn.net/?f=E_i%20%3D%20E_f)
so:
![\frac{1}{2}K_1X_1^2 = \frac{1}{2}K_2X_2^2](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7DK_1X_1%5E2%20%3D%20%5Cfrac%7B1%7D%7B2%7DK_2X_2%5E2)
where
is the constant of the spring 1,
the compressed of the first spring,
is the constant of the second spring and
is the compressed of the second spring.
Replacing values, we get:
![\frac{1}{2}(553N/m)(0.1m)^2 = \frac{1}{2}(370N/m)X_2^2](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%28553N%2Fm%29%280.1m%29%5E2%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28370N%2Fm%29X_2%5E2)
Solving for
:
![X_2 = 0.122m](https://tex.z-dn.net/?f=X_2%20%3D%200.122m)
Newton's first law of motion is an object in motion stays in motion until acted upon by another force. Driving at 30 mph in a car is going to stay constant until you crash the car into a wall, stopping the car.
