An astronaut in her space suit has a mass of 87.0 kg. her tether loses its attachment to her spacecraft while she is on a spacewalk. initially at rest (with respect to her spacecraft) she throws her oxygen tank, which has a mass of 12.0 kg, away from her spacecraft with a speed of 8.00 m/s to propel her back towards it. (a) determine the maximum distance she can be from the craft and still return withn 2.00 min( the amount of time the air in her helmet remains breathable). (b) explain in terms of newton's laws of motion why this strategy works.
