The first figure gives spring force F, versus position x for the spring-block arrangement of the second figure. The scale is set by F,- 180 N. We release the block at x 13.0 cm. How much work does the spring do on the block when the block moves from x+8.0 cm to (a) x=+5.0 cm, (b)x=-5.0 cm, (c) x-8.0 cm, and (d) x=-11.0 cm?

The first figure gives spring force F, versus position x for the spring-block arrangement of the second figure.
The scale is set by F, = 180 N. We release the block at x 13.0 cm. How much work does the spring do on the
block when the block moves from x=+8.0 cm to (a)x=+5.0 cm, (b)x= -5.0 cm, (c) x = -8.0 cm, and
(d) x=-11.0 cm?
