A 0.1 kg mass is connected to a spring with a spring constant of 100 N/m. The spring is stretched a displacement of 0.2 meters and released. What is the total energy in this system?*

2.0)
4.0J
10.0)
20.03

Explanation:

The elastic potential energy of a spring is given by:

, where is the spring constant and is the displacement from equilibrium.

Solving for , we get:

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
