Question
Sorry for the re-post but I really need to know this, but now I just want to know if the question is right.
A spring with a force of 5.2 N/m has a relaxed length of 2.45. When a mass is attached to the end of the spring and allowed to come to rest. the vertical length of the spring is 3.57m. Calculate the elastic potential energy stored in the spring.
I got 3.26144
from 1/2* 5.2*1.12^2
Please help.

Looks good to me, but do not give the answer to 6 places after the decimal point. Something like 3.26 is plenty.
Ok thanks for the advice, now I can go to sleep.
