The diagram below shows a one-dimensional row of 5 microscopic objects each of mass 5 ✕ 10−26 kg, connected by forces that can be modeled by springs of stiffness 10 N/m (so each object can be modeled as if it were connected to a single spring of effective stiffness 4ks = 40 N/m -- neglect any possible differences for objects near the ends). These 5 objects can move only along the x axis.
