A neutron star has a mass of 2.0 10³⁰ kg (about the mass of our sun) and a radius of 5.0 10³ 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 0.019 m? (Assume that the gravitational force is constant over the distance of the fall and that the star is not rotating.)
