1. The problem statement, all variables and given/known data two persons on ice skates stand face to face and then push each other away. their masses are 52 kg and 77 kg. what is the total momentum after they have pushed off 2. Relevant equations the equation that would be most useful here would be P=Pa+Pb the equation for total momentum 3. The attempt at a solution Im stump on this problem. Two mass are given, but no velocity is displayed. can someone explain to me.
