A meteoroid with a mass of 5840 kg is detected heading toward the Earth, which has a mass of 5.98×1024 kg. Its speed at a distance of 3.85×108 m from the center of the Earth (roughly the distance to the Moon), is 1000 m/s. Fortunately, it misses the Earth by a distance of 9.77×106 m, measured from the Earth's center. How fast was the meteoroid traveling when it came closest to the Earth? The effects of the Sun's and Moon's gravity can be ignored. (in m/s)
