Exercise 3.1.105: suppose two masses on carts on frictionless surface are at displacements x1 and x2 as in the example of this section. suppose initial displacement is x1(0) = x2(0) = 0, and initial velocity is x0 1 (0) = x0 2 (0) = a for some number a. use your intuition to solve the system, explain your reasoning.
