1. The problem statement, all variables and given/known data Problem - Find the following: a. Potential energy in a fully compressed plastic spring. b. Spring constant This was a lab and we're supposed to do it at home, here are the variables I have measured: spring height when not compressed: 0.115 metres. spring height when completely compressed: 0.0450 metres mass of spring: 0.0148kg 2. Relevant equations Hookes Law: Ep = 1/2kx^2 Fs = mg 3. The attempt at a solution The answers we got seemed extremely low. A)1/2(2/074N/m)(0.07m)^2 = 0.00508J B)(0.0148kg)(9.81m/s^2)/0.07m = 2.074N/m Any help would be great.
