(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Fire at angle 45 degree.

Initial kinetic energy = Eo

At top of projectile explode with addtional energy Eo into 2 fragment.

1. Mass = m1, go straight down.

2. Mass = m2, direction: unknown.

Question:

1. Velocity (mag and dir) of m2

2. Velocity of m1

3. What's ratio m1/m2 when m1 is maximun?

2. Relevant equations

Conservation of momentum:

mo x vo = m1 x v1 + m2 x v2

Eo = 1/2 mo x vo^2

mo = m1 + m2

Center of Mass:

No clue

3. The attempt at a solution

Ok, so I set up the conservation of momentum formula. Now what? How can I find the direction of m2? How can I use center of mass formula? Thanks!
