Consider four different oscillating systems, indexed using i = 1 , 2 , 3 , 4 . Each system consists of a block of mass m i moving at speed v i on a frictionless surface while attached to an ideal, horizontally fixed spring with a force constant of k i . Let x denote the displacement of the block from its equilibrium position. Order the systems from largest total mechanical energy to smallest.
