A Space Walk An astronaut is taking a space walk near the shuttle when her safety tether breaks. What should the astronaut do to get back to the shuttle? View Available Hint(s) Attempt to "swim" toward the shuttle Take slow steps toward the shuttle Take a toal from her tool belt and throw it away from the shuttle. Take the portion of the safety tether still attached to her belt and throw it toward the shuttle Previous Answers Completed Part B Assuming that the astronaut can throw a tool of any inertia with the same acceleration, what tool should be thrown to get back to the shuttle as quickly as possible? View Available Hint(s) Hint 1. How to approach the problem Recall that during an isolated interaction between two objects, the changes in momentum for the two objects are equal and magnitude and opposite in direction. Furthermore, since the time interval in which they interact is the same, the time rates of change in momentum are also equal in magnitude and opposite in direction, which can be expressed as follows (written in terms of x components): 1a-22 Therefore, how will changing the inertia of the tool affect the astronaut's acceleration (such that it is larger)? The tool with the smallest inertia The tool with the largest inertia. Any tool, since the inertia of the tool would make no difference
