Suppose a 2 million kg meteor is initially basically at rest in the asteroid belt, at a distance of 4.0 x10% km from the Sun. As it falls toward the sun it collides with the Earth (ending up 1.5 x 108 km from the Sun). a) What is its Kinetic Energy at impact? (Assume throughout that only the gravity of the Sun matters). b) Compare your result with the fact that the most powerful fission bomb explodes with an energy of 2.1 x 1015J and that the heaviest asteroid is Ceres which has a mass of 9 x 1020 kg. c) What effect does the assumption we made in (a) have on your result? That is, would the real energy of impact be higher or lower if we do not make this assumption?
