An unfortunate astronaut loses his grip during a spacewalk and finds himself floating away from the space station, carrying only a rope and a bag of tools. First, he tries to throw a rope at 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 ma=113 kg and the bag of tools has a mass of .mb=13.0 kg. If the astronaut is moving away from the space station at vi=1.20 m/s initially, what is the minimum final speed ?b,f of the bag of tools with respect to the space station that will keep the astronaut from drifting away forever? calculate vb,f in m/s
