Hi everyone, this problem is truly pain in the a**. I understand that Newton's third law applies here, but whatever I have tried nothing worked out. I know that the force applied is the same in magnitude, but opposite in the direction and accelerations of these two masses are different.....but no luck. Can anyone please help me out? At a time when mining asteroids has become feasible, astronauts have connected a line between their 3090-kg space tug and a 5770-kg asteroid. Using their ship's engine, they pull on the asteroid with a force of 510 N. Initially the tug and the asteroid are at rest, 550 m apart. How much time does it take for the ship and the asteroid to meet?
