still be travelling at a speed? At what speed should a space probe be fired from the Earth if it is required to still be travelling at a speed of 6.75 km/s, even after coasting to an exceedingly great distance from the planet (a distance that is essentially infinite)? (Neglect the friction and drag in the atmosphere.)

Please answer in km/s
