How much energy can be stored in a spring with k = 400N/m if the maximum possible stretch is 12cm?
U = 1/2k(x^2)
The Attempt at a Solution
I tried using the above equation. U = 1/2(400)(.12^2) = 2.88.
Great, just when I learn how to do significant figures, the computer wasn't looking for 'em. That figures!Holy crap everyone!! I am so sorry about this problem. I was just going to try entering 3, when I noticed that I didn't put the decimal point into my original answer. BIG difference between 288 and 2.88! Sorry again!!!!!
