If two skaters are pushing away from eachother i know that their momentum will be equal but in opposite directions. However, if they have different masses (i.e. one is 60kg and another is 72kg) will that affect the momentum?? :rofl: Original question: Two skaters stand facing each other. One skater's mass is 60 kg, and the other's mass is 72 kg. If the skaters push away from each other without spinning, the lighter skater has less momentum. their momenta are equal but opposite. their total momentum doubles. their total momentum decreases.
