# 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 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 ma=113 kgma=113 kg and the bag of tools has a mass of mb=13.0 kg. mb=13.0 kg. if the astronaut is moving away from the space station at =1.20 m/svi=1.20 m/s initially, what is the minimum final speed ,fvb, f of the bag of tools with respect to the space station that will keep the astronaut from drifting away forever?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
