Homework Equations
[K + Eg + Es] = [K + Eg + Es + Ef]
Initial Final
K=1/2mv^2
Eg=mgh
Es= 1/2 kx^2
Ef= uND
The Attempt at a Solution
What I did: [K] = [K + Eg]
or either [ Eg] = [K}. Please help me with setting this problem up. The first set up didn't work for me and I'm just needing help setting the problem up. No need for figuring out the problem. Thank You
