Homework Statement
Find the energy stored in a spring when stretched .05m, and .10m. Spring Constant of 67.21 N/m.
(I am given a graph)
Homework Equations
F=1/2kx^2
The Attempt at a Solution
Ok, to find the energy stored I believe I am going to need the distance (.05m, and .10m) and the spring constant. Is there a way to calculate energy stored with just this? I am given a graph but the Force vs. Distance (in meters) only goes up to 0.3m so I can't rely on the graph just by looking at it.
