Need answers to this question so that i can compare your solutions to mine. This is question on Gravitational force and potential
Two uniform spheres with identical diameter d = 8.00 cm but different masses m1 = 25.0 kg and m2 = 65.0kg are located in deep space (far away from other masses) at a distance of r = 40.0 m. The spheres are released from rest and accelerate towards each other because of their mutual gravitational attraction.

a) Calculate the relative velocity with which one sphere is approaching the other when their centers are 10.0m apart,

b) When they collide with each other.
N cre your solutions to mine. This is question on Gravitational force and potential
