Homework Statement

gives spring force Fx versus position x for the spring–block arrangement
http://edugen.wiley.com/edugen/courses/crs1650/art/qb/qu/c07/pict_7_11.gif
The scale is set by Fs = 160 N. We release the block at x = 16.0 cm. How much work does the spring do on the block when the block moves from xi =+8.0 cm to x=+7.0 cm
Homework Equations
Fs = -kd
W = Fd
The Attempt at a Solution
Fs/d = k
160N/0.16m = k
1000 = k
kd = F
1000*1m = 1000N
1000N * 1m = W
W = 1000J
I don't know how to this question please help.
