(a) Find its spring constant

I found the correct answer to be k=784 N/m

(b) The load and the spring are taken down. Two people pull in opposite directions on the ends of the spring, each with a force of 170 N. Find the length of the spring in this situation.

I thought the answer was 0.7937m but this is incorrect. I have no other idea on how to solve for part b.

Thank You!

**drwls**, Tuesday, February 2, 2010 at 3:41amThe length of the spring under tension is the amount of stretching PLUS the original unstressed length.

The stretch amount is F/k = 170/784

= 0.217 m = 21.7 cm

Add 36.0 cm to that.
