Find the euler–lagrange equation describing the brachistochrone curve for a particle moving inside a spherical earth of uniform mass density. obtain a first integral for this differential equation by analogy to the jacobi integral h. with the of this integral, show that the desired curve is a hypocycloid (the curve described by a point on a circle rolling on the inside of a larger circle). obtain an expression for the time of travel along the brachistochrone between two points on earth’s surface. how long would it take to go from new york to los angeles (assumed to be 4800 km apart on the surface) along a brachistochrone tunnel (assuming no friction) and how far below the surface would the deepest point of the tunnel be?
