You compress a spring by a certain distance. then you decide to compress it further so that its elastic potential energy increases by another 50%. what was the percent increase in the spring's compression distance?
Elastic potential energy = 1/2 k * change of x^2 k- coefficient x - change in length. to increase energy 1.5 times you have to change x (compress) into [tex] \sqrt{1.5} [/tex] times (it's abot 1.22 or 22%)
