  It is a Question!
  Astronaut jennifer's lifeline to her spaceship comes loose and she finds herself stranded at a constant 100.0m from the spaceship. She throws her 2.00 kg wrench at 20.0 m/s in a direction away from the spaceship. If she and her spacesult have a combined mass of 200 kg how long does it take her to coast back to her spaceship?

  Conservation of momentum tells us that her velocity is 0.2 m/s (the ratio of
  wrench mass to her mass times the wrench velocity) towards her spacecraft,
  so she takes 100/0.2=500 s to reach the spacecraft.
