A light source lies at the bottom of a pool of water. It emits a beam of light that strikes the interface between the water and an unknown medium at 45 degree. The index of refraction of water is n = Take the point where the light beam strikes the interface to be the origin of the x-y coordinate system. The marked grid unit is 1.0 so the source is located at x = -2 m, y = -2m.
a. If the refracted ray passes through A, what is the index of refraction of the top medium?
b. If the refracted beam passes through A, how much time does it take light to get from the source to point A?
c. If instead, the refracted ray passes through B, what is the index of refraction of the top medium?
d. If the refracted beam passes through B, how much time does it take light to get from the source to point B?
e. What would the index of refraction of the unknown medium have to be for all the light to be totally internally reflected so it passed through point C? Is this possible? Justify our answer.

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.
