An object of mass m is launched with a magnitude of velocity v0 from the surface of a planet with mass M and radius R. The object travels a distance kR from the center of the planet (k > O). Instantaneously, the planet teleports next to the object. The object then begins to circle around the planet's center uniformly. What is the distance (d) between the object and the center of mass of the planet-object system? Your answer must contain only m, M, R, k, and fundamental constants, as needed
