What is the relationship between the distance between objects and the force of gravity between them in newtons law

Observations show that interstellar clouds can have almost any shape and

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
