Two uniform  spherical starts made of same material have radii R and 2R. Mass of the smaller planet is m. They start mmoving from rest towards each other from a large distance under mutual force of gravity. The collision between the stars is inelastic with coefficient of restitution 1/2.    The maximum separation between their centres after their first collision
