Homework Help: Physics Help PLEASE!!!

Posted by Jael on Tuesday, November 30, 2010 at 2:48pm.

A spring that is 0.7 m in length elongates to 1.06 m when a 20 Newton force is exerted to stretch the spring. By how much more does the spring stretch when an additional 8 Newtons of force is exerted on it?

1.01
0.053
0.072
0.45
0.144
0.561
0.736
1.06

I think there are 3 parts to figuring this out:

#1) 20 N + 8 N + 28N
#2) idk...
#3) idk...

Please help!
