## Homework Statement

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.

## Homework Equations

0 = mv1 + mv2

## 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!
