1. The problem statement, all variables and given/known data An astronaut is pushed from her ship at a velocity of 2m/s. Her weight including her tool belt is 120kg. Remembering newtons 3rd law, she takes 5 seconds to decide to detach her belt and throw it away from her. The 20kg tool belt leaves her suit as she throws it in front of her 10m/s. If she has 20 minutes of air left in her tank, does she make it? 2. Relevant equations Conservation of Momentum mvi=mvf Distance d=vt 3. The attempt at a solution I say that the astronaut survives. Because of distance equation= (2)(5)=10m Her initial momentum is 240kg m/s And by throwing the belt in front of her she is propelled at -.4m/s Since she only traveled 10m she would make it back on time.
