Homework Equations

Et = Ek + Eg + Ee

The Attempt at a Solution

Top:[/B]
Et=mgh+1/2k₁ Δx₁² +1/2k₂Δx₂²

196h+400+600 = E_T

Bottom:
Et=1/2k₁Δx₂²+1/2k₂Δx₂²

400+600=1000

...and that's when I realized I must have done something wrong. Sorry, I'm kind of bad at this stuff. Please help

Why do you think you have done something wrong?
h, I assume, is the distance the mass falls. What is the relationship between h and x₂?
