Astronaut Jennifer's lifeline to her spaceship comes loose and she finds herself stranded, "floating" \(100\,\text{m}\) from the mothership. She suddenly throws her \(2.00\,\text{kg}\) wrench at \(20\,\text{m/s}\) in a direction away from the ship. If she and her spacesuit have a combined mass of \(200\,\text{kg}\), how long does it take her to coast back to her spaceship?
