Pushing on the pump of a soap dispenser compresses a small spring. When the spring is compressed 0.54 cm, its potential energy is 0.0025 J.
(a) What is the force constant of the spring?
kN/m
(b) What compression is required for the spring potential energy to equal 0.0075 J?
cm

pe= 1/2 k x^2 solve for k
thank you. i just got it, but i can not seem to get part b.
would it be .0075=1/2*1714.7*x^2
would it be .0075=1/2*1714.7*x^2
