## Homework Statement

A particle of mass 5m moving with speed v explodes and spilts into two pieces with masses of 2m and 3m. The lighter piece continues to move in the original direction with speed 5v relative to the heavier piece. what is the actual speed of the lighter piece?

## Homework Equations

using law of conservation of linear momentum

initial moment = final moment

mass (m) x Velocity (v) = mass (m) x Velocity (v)

## The Attempt at a Solution

using the formula...

5m (v) = 2m(v) - 3m (5v) ....) i used the minus (-) sign because the heavier piece went a different direction

5mv = 2mv -15mv

20mv = 2mv

10v = v

but my answer was wrong....

PLEASE HELP EXPLAIN WHY AND WHAT IS IT IM MISSING TO DO>>>
