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
The Attempt at a Solution
I'm required to obtain K first before proceeding to the next step.
k= - Fs/d
= 1428.57 N/m
K= spring constant
But the answer is wrong. May I know the reason ? Thank you.
