(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The scale is set by Fs = 200 N. We release the block at x = 14.0 cm. How much work does the spring do on the block when the block moves from xi =+8.0 cm to (a)x=+7.0 cm, (b)x=-7.0 cm, (c)x=-8.0 cm, and (d)x=-11.0 cm?

xi= initial point

x= final point

2. Relevant equations

3. The attempt at a solution

I'm required to obtain K first before proceeding to the next step.

Fs= -kd

k= - Fs/d

= 200/0.14

= 1428.57 N/m

K= spring constant

d=distance

But the answer is wrong. May I know the reason ? Thank you.
