A. Write down a differential equation that describe the motion of the two masses. Rewrite the differential equations as a system of first/order differential equations, x=Ax+c, where x is in R in n dimensions.B. Ser part A for definition of y. What is the equilibrium point x* ?

also to the massless point at which the two springs are com Consider two masses each of mass m attached between two walls a distance d apart (refer to Figs. 9-3 and 9-7): LL Figure 9-7. Assume that all three springs have the same spring constant and unstretched length
