Question
A spring has a force constant of 554.1 N/m. Find the potential energy stored in the spring when the spring is a) stretched 4.35 cm from equilibrium. Answer in units of J.
b) compressed 2.98 cm from equilibrium. Answer in units of J.
c) unstretched. Answer in units of J.
I did 1/2 k x^2 but its wrong

a) PE=1/2 kx^2
b) PE=1/2 k x^2
c) zero.
change stretching distance to meters. I suspect that is what you did wrong.
