I attached the problem statement only with PART of the solutions.
He is using the conservation of energy to find the velocity of the anvil.
T=Kinetic energy
V sub e=potential energy of the spring
V sub g=potential energy of gravity
The part I am not understand is how ΔV sub e = 1/2(2.8*10^6)(0.024)^2+29.4(10^3)(0.024) J
Why do they have the 29.4(10^3)(0.024) there?? That's potential energy of gravity. My professor said the answer was right and that he has checked over it, but he takes a long time to respond so I'm asking it on here.
