A satellite in a circular orbit of radius 8 times the radius of the earth is completely stopped and then let go so that it falls radially towards the earth. A tunnel is built from the surface of the earth to its centre so that the satellite can pass through that tunnel without collision. Neglect the rotation of the earth and assume that the earth's gravity is the only relevant force. The speed of the satellite, in km
