Two astronauts are working outside the International Space Station. They are separated by a distance of 12 m when they get upset with one another and start fighting. Astronaut 1 (m1 = 170 kg including spacesuit) throws a 3 kg wrench at a velocity of 5 m/s towards Astronaut 2 (m2 = 155 kg including spacesuit). At that very same instant, Astronaut 2 fires her jet pack so that she is traveling towards Astronaut 1 at a constant velocity of 2 m/s. Astronaut 2 is able to catch the wrench and continue floating toward Astronaut 1. How much time elapses between the instant Astronaut 1 throws the wrench and the time Astronaut 2 catches up to him?
