1. The problem statement, all variables and given/known data http://edugen.wiley.com/edugen/courses/crs1650/art/qb/qu/c07/pict_7_36.gif 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 2. Relevant equations Fs = -kd W = Fd 3. 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.
