Answer:
The total energy of the SHM in the spring, Etot, is equal to the potential energy of the spring when it is maximally stretched. It is because in that case there is no kinetic energy and the entire mechanical energy comes from U. So we have, Etot = ½ kA2. When the object is at x = A/2, U = ½ k(A/2)2 = Etot/4.
