First he tries to throw a rope to his fellow astronaut, but the rope is too short. In a last ditch effort, the astronaut throws his bag of tools in the direction of his motion (away from the space station). The astronaut has a mass of 135 kg and the bag of tools has a mass of 13.0 kg. If the astronaut is moving away from the space station at 1.20 m/s initially, what is the minimum final speed of the bag of tools (with respect to the space station) that will keep the astronaut from drifting away forever? Number m/ s Previous Give Up & View Solution e Check Answer e Next Exit Hint

Explanation / Answer

Sinc eno external forces momentum of system can be conserved

Final velocity of astraunet should be zero

(135+13)1.2 = 13V + 135x0

V=13.36 m/s
