A 60kg astronaut is on a space walk away from the shuttle whenthe tether line breaks. She is able to throw her 10kg oxygentank away from the direction of the shuttle with a velocity of12.0m/s to propel herself back to the shuttle. Assume thatshe starts from rest(relative to the shuttle), determine the maximum distance she can be from the craft when the line breaks andstill return within 60 seconds(the amount of time that she can holdher breath).
