1. The problem statement, all variables and given/known data An object at rest on a flat, horizontal surface explodes into two fragments, one seven times as massive as the other. the heavier fragment slides 8.2m before stopping. how far does the lighter fragment slide? Assume that both fragments have the same coefficient of kinetic friction. 2. Relevant equations 0 = mv1 + mv2 3. The attempt at a solution The initial momentum is 0 in this question because there is no movement initially. using the equation 0 = mv1 + 7mv2 -mv1 = 7mv2 -v1 = 7v2 but... the problem im having is how do i incorporate the distance ? help!
