# Calculate kinetic energy in separation between two uniform spheres during gravitation.

From an inertial frame in space, we watch two identical uniform spheres fall toward one another owing to their mutual gravitational attraction. Approximate their initial speed as zero and take the initial gravitational potential energy of two-sphere system as Ui. When the separation between the two spheres is half the initial separation, what is the kinetic energy of each sphere?
