An educational toy company, “EPH Swartz!” is looking for a new toy that will revolutionize the toy market. Your job is to design and construct a creative toy based on physics that you feel will be widely in demand and increase revenue for the company and you do a write-up paper that includes how the idea arose for the toy (1Page), a description of the physics behind the toy’s function & GPS correlation, extremely detailed (at least 2Pages) and instructions for how to use the toy or play the game (must be clear and precise).

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is

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.
