so here we have a spring with a given stiffness we have a block with a given mass and if the block is subjected to this force we need to determine its velocity when the block has moved a distance of half a meter and when s is equal to zero the block is at rest and the spring is uncompressed so what this telling me is that we can model this spring force here with our equation negative K X or X I'm going to use X instead of s where X is a position variable that is counting positive this way and negative one two three four this way it's always good to test this out just make sure your equation holds if I move this block this way it'll be moving a positive x and if my X here is positive like positive 2 and my K is always positive like maybe three my force will be negative because of this negative sign which should make sense because that force has to be pushing the block this way in the neg
