${?}^0$ Consider four different oscillating systems, indexed using $i=1,2,3,4.$ Each system consists of a block of mass $m_1$ moving at

speed $v_i$ on the same frictionless surface while attached to an ideal, horizontal spring with a force constant of $k_i$ that is fixed at its other end.

Let $x$ denote the displacement of the block from its equilibrium position and A denote the maximum oscillation amplitude. Order the systems from largest total mechanical energy to smallest.

Assume that the surface defines the zero reference point for gravitational potential energy.
