Two masses m1 and m2 slide on a horizontal frictionless surface, connected by a spring with force constant k. Show that the frequency of oscillation for the system is omega = Consider only motion in one dimension (Hint: consider Newton's Third Law; express the forces in terms of x = x2 - x1- L. where x2 and x1 are coordinates of m2 and m1 and L the original length of the spring.
