Find final speed of the astronaut after throwing the tank

Click For Summary

Homework Help Overview

The problem involves an astronaut in space who throws an oxygen tank, and the goal is to determine the astronaut's final speed after the throw. The context is centered around the principles of physics, particularly conservation of momentum.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the application of conservation of momentum and question the initial conditions and values given in the problem. There is also a humorous remark about the speed of the tank, suggesting some uncertainty about the problem's parameters.

Discussion Status

The discussion is ongoing, with some participants suggesting the conservation of momentum as a relevant principle. There is no explicit consensus on the approach or the values involved, and multiple interpretations of the problem are being explored.

Contextual Notes

Participants are considering the implications of the astronaut starting from rest and the accuracy of the given speed of the oxygen tank. There is a general sense of questioning the problem's setup and values.

A 64.1 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 11.7 m/s propelling the astronaut back to the shuttle. Assuming the astronaut starts from rest, find final speed of the astronaut after throwing the tank. Answer in units of m/s

What principle do you think you should apply?

Damn that's fast! Are you sure its not like 1.17 m/s or is the question just stupid? :biggrin:
 
:rolleyes: ok here you go

use: Conservation of momentum

mass of oxygen tank X speed of oxygen tank = mass of astronaut X speed of astronaut
