Make a Claim as to whether momentum is conserved or not conserved. Identify the Evidence that provides support for your claim; refer to specific sets of values in each data table that serve as credible evidence. Write a paragraph or more of sound Reasoning to argue why the evidence logically leads to the claim you are making. Write well. Write logically. Write thoroughly. Use a separate page of paper if necessary.

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
