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?
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
How can I use center of mass correctly to get the direction of m2? I can set up the conservation of momentum formula but I need the second formula to solve for the 2 velocity!
