Homework Help: Check for me this solution in General Physic

  1. Sep 29, 2010 #1
    I reckon that we only apply conservation of linear momentum for object which has total net force acting on equal zero but in this case , the gravity force still exist , total net force is mg
    Thank in advance

    Is there a missing illustration? Because you haven't presented a problem.

    I was not upset; I was only pointing out why you were not getting replies.

    I think I understand your concern. The question seems to me to be written to avoid the force of gravity by stating "right after the explosion." The focus is on momentum. Gravity only enters into what you posted in the Exercise, even then it's a path that's straight up and down and only asks about "the center of mass."
