Two hypothetical planets of masses m1 and m2 and radii r1 and r2, respectively, are nearly at rest when they are an infinite distance apart. Because of their gravitational attraction, they head each other a collision course. When their centre to centre separation is d, find an expression for the speed of each planet and for their relative speed.
