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.
