1. The problem statement, all variables and given/known data An space traveler is eating his lunch in his spaceship when he realizes he has drifted into the middle of the room and can not grab any of the walls. Stuck, floating without gravity to pull him to the floor, he comes up with an idea. He realizes that if he starts throwing his lunch in one direction, he will float the other way due to conservation of momentum. He quickly calculates that if he throws his entire lunch at once, he will float at a speed of 1 m/s towards the wall. However, the crafty spaceman doesn’t want to part with his Meatloaf. How fast can he float towards the wall if he throws everything in his lunch except his meatloaf? Assume he weighs 150kg and the meatloaf weighs .5kg. 2. Relevant equations Not sure 3. The attempt at a solution Not sure where to begin. Thanks for the help.
