Question #22832
USE conservation of momentum for- mula. The astronaut will have the same mo- mentum as the oxygen tank - only in the reverse direction. —— A 62.5 kg astronaut is on a space walk when the tether line to the shuttle breaks. The astronaut is able to throw a 11.0 kg oxygen tank in a direction away from the shuttle with a speed of 11.4 m/s, propelling the astronaut back to the shuttle. Assuming that the astronaut starts from rest, find the final speed of the astronaut after throwing the tank. Answer in units of m/s
Expert's answer
The equation for theconservation of momentum:
62.5 kg * (-v) + 11.0 kg * 11.4 m/s = 0;
v = 11.0 kg * 11.4 m/s / 62.5 kg = 2.006 m/s

Answer: 2.006 m/s
