- $\begingroup$ Hint: 1st: velocity $ v=d/t $, substitute in distance and time to find the required velocity. 2nd: momentum is conserved. $ p=mv $ for both the astronaut and the spanner, equate them. Rearrange to solve. All the best ;) $\endgroup$qftme– qftme2011-05-18 12:21:02 +00:00Commented May 18, 2011 at 12:21

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. quantum-mechanics), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
