- A 1000 kg object is found heading towards the Earth. At the moment it is 4 Earth radii away from the surface of our planet the asteroid is moving at 100 m/s. If it collides with our planet, how fast will it be moving right before it hits the surface? How much kinetic energy is going to be released in this collision?**68 @ Two small spaceships, each with mass m = 2000 kg, are in the circular Earth orbit of Fig. 13-51, at an altitude h of 400 km.
