At a time when mining asteroids has become feasible, astronauts have connected a line between their 3220-kg space tug and a 6400-kg asteroid. Using their ship's engine, they pull on the asteroid with a force of 490 N. Initially the tug and the asteroid are at rest, 480 m apart. How much time does it take for the ship and the asteroid to meet?
