Question 82492: So Iwould like to just check my answer to this problem. What did you get? A load of 8kg attached to the bottom of a coil spring stretches the spring to a length of 76 cm, and a load of 14kg stretches it to a length of 85cm. Find the natural (unstretched) length of the spring. Answer by scott8148(6628) (Show Source):
You can put this solution on YOUR website! the distance a spring stretches is directly proportional to the load (or force) on the spring x=kf
let L equal the unstretched length ... so L+8k=76 ... and L+14k=85
multiplying the first equation by 7/4 and subtracting the second equation gives (7/4)L+14k-(L+14K)=(7/4)76-85
