Suppose the act of throwing the tool takes the austronaut 0.7 seconds, that is she applied a force to the tool before it leaves her hand. What velocity toward the space shuttle will that have given her? And if she was 12m away from the shuttle to start with, how long will it take her to reach the shuttle?
