A neutron star has a mass of 2.0 x 1030 kg (about the mass of our sun) and a radius of 5.0 x 103 m (about the height of a good-sized
mountain). Suppose an object falls from rest near the surface of such a star. How fast would this object be moving after it had fallen a
distance of 0.012 m? (Assume that the gravitational force is constant over the distance of the fall and that the star is not rotating)
